Ok. Let me take a shot at responding to this. The answear is yes. Or maybe no. Wait, maybe? After several beers I think the answear is-------- "squirrel "!

Sometimes.
When it is not give me the strength to end it.

First define suffering in this context

No, but don’t stop living, stop suffering.

4 simple little words - 1 big big question.

I think it's a very individual being-specific answer.

If someone (human or otherwise) is living a fulfilling life with pleasures and love and contentment, and the suffering is minimal, the answer is easy... YES

If someone's life is horrible with no pleasure or love or contentment, only suffering, pain, torture (physical & mental), hate, and with no hope that ever changing, the answer is probably No.

There is, however, a vast continuum between those two points and everyone is somewhere on that continuum with some degree of Yes and No. Each individual assesses, for themselves, their personal situation and where they fall on that line... how close they are to the Yes or No.

For me, it's a day by day, sometimes moment by moment evaluation.
So far, I've come up with "Yes" more often than not.
So my answer, at least at for today, is "Yes".

To be or not to be. That is the question.

It is worth living if your life has an acceptable quality or hope of that, but if it is simply suffering, then better to end it.

That seems another way of asking the existential question of whether life is worth living or not and should one then commit suicide if it is not?

I guess that would be determined by the kind of suffering and if there was going to be an end to it, or if your entire life was going to be great suffering. I am sure there are people in many 3rd world countries where life is nothing but suffering that they would say NO, it is not worth it.

YOU BET YOUR sweet ass it is...NEED you ask???

Having been ill for the past fifteen months, I have had more than my fair share of time to contemplate your question. Despite my attempt to internalize the Buddhist underpinning that life IS suffering, I still struggled mightily to convince myself that what I was going through was worth it. I also tried to remind myself that my suffering was temporary, that someday I wouldn't feel quite as defeated as I had felt every single day for almost a year and a half.

Had I had no hope for recovery, I would have asked Palliative Care to take me off of the drugs that were keeping me alive, and just focus on managing my pain so that I could die peacefully.

I suppose quality of life is the key issue, and when humans are suffering, they're typically unhappy and ready to call it a life.

Didn't mean to over-personalize my response, just really feeling your question.
