No but tired of social structures that serve very few....

I can't lose something l never had.

In an age when all of our politicians are bought by big money and the powerful and wealthy seem to want more and more at the expense of us, it is difficult to believe in humanity. That said, I see underpaid teachers work their butts off because they care about their students and want the best for them. Day after day they quietly go about their business enlightening young minds. I also watch them spend some of their hard earned money to help a student who needs food or clothes. I see these because I am a teacher in the lowest paying state in the land for teachers. Believe me, there are good people out there. We may not always notice their good deeds.

Love your self and the people that love you and everything will fall in place.

I have no faith of any type. I hate the concept of faith. I have my understanding of humanity as being lead towards selfish ends or being lead towards an altruistic purpose. The key word being lead. Humanities "fate" (another word I hate) is going to be determined by the leadership of this world. If our leaders continue to be Trumps, Putin's, Kim Jong-un's Theresa May's we are not going to fair very well.

Well, if it helps any, we haven't changed much...humanity, that is....we are actually at the 'getting to know each other stage' of global connectivity. It's kinda like an open house party, at first, there are a lot of struggles....but once we get to accept how weird our neighbors are, and maybe share a bit of their weirdness, we'll get along just fine....or....well, we'll stick with 'we'll get along just fine'....hehe

After skimming through the responses to your post I think plenty of evidence has been presented that "Humanity" is not a lost cause. I would add to this, however, that Humanity is made up of Humans, individuals. So it's important to remember that our "collective" efforts are almost never in-concert with each other. There are many, many individuals and organizations doing good things (and opinions on what's "good" will also differ wildly). So my advice is for you to have faith in yourself. You can't control anyone else. If enough individuals do the "right things," Humanity will be alright. =]

I am not sure that I have much faith in humanity. We are all false information and "monkey see - monkey do."

How about the fact that there are still people out there trying to do good for humanity in the face of all the shittiness of it? I think as long as there are people trying, no matter how bad it gets, speaks volumes about us and how valuable we really are.

I have not lost faith in humanity; however, we face at least three three things that challenge our existence, climate change, the emergence of AI, and environmental damage. These things may seem to be a perfect storm that is unavoidable, and it is easy to say humanity will fail to solve these issues; thus, wiped from the face of the Earth. However, IMO there is hope.
I see AI playing a key role in climate change remediation. Automated factories to build electric vehicles are already being used, and more are being built. Renewable energy devices are being built in evermore automated factories. And, food production factories will grow things locally and shorten distribution lines; some are already in use and more are being constructed. Food production factories will reduce the amount of water used to grow food; thus, freeing water for people. Automation will extend become ubiquitous. 
As economies electrify, climate will become worse, and remediation efforts will begin. IDK how yet, but suggestions include a vast shade in space to block sunlight. 
Once climate change is under control, we still must learn to live with our environment, instead of raping it. Again, technologies exist to lessen our impact on the envoronment, and to improve the environment. We need to adopt to them or adapt to them. 
The final issue may be contending with super smart AI that can either help us or destroy us. I believe AI will create a post scarcity civilization, in which everyone has basic necessities, and a better life reqruies effort. But, there are no guarantees. 

I don't know if this is the right ballpark I am in, but I seriously mistrust my own Government (London and Northern Ireland). I feel I am being fed fake news, I feel I don't have a community any more even though I live in a sheltered housing scheme - also I have Hyperacusis which means Loud noises are really troubling for me and send me a bit dotty and no one recognises this .

My Housing Association is off the chart for just doing stuff without consulting us even though we are the ones who have to live here and pay for that privilege and I realise to that the word community can be bandied about but mean nothing. so many things just happen- to us and htis asn tthe case when I came here - Consulatation was key! Safety was key!

It can seem at times that humanity has corsened and hardened especially of late. "The evil men do," said Shakespeare, " lives after them. The good is often intered with their bones." Bad things make good press. So it's easy to be bombarded by sad news. In the end the only thing a person can do is to be the person you want to see in others. Not only does one become the army of one, but others of like mind and heart will be drawn in and the army will grow in numbers and strength. In short, don't lament the loss of kindness, be kind.

I feel this way a lot especially since my divorce and trying to date. I guess for me it's seeing my beautiful 19 year old son who is one of the most kindest person I know. I think you might just need to identify the specific situations that are giving you these feeling and try to take a break from them if you can.

Don't have faith in humanity, that's for suckers.

Instead know that we are all foolish at times and need a bit of forgiveness from eachother.

I have felt the same way myself. Usually I have watched to much network news when i find myself thinking this way.

Too much TV and media exposure has that effect on me
