What have you done for yourself to be noticed? I still go to AA retreats just to see and maybe help another in recovery. Its a cheap weekend get away at a campground with shared cabins and large bathrooms. It's a meeting place to begin with. Another form of getting to meet people is (adult camping). Check it out on the web. It's pricey but it's fun. One pay covers lodging and food. Something like this gives you that extra push to diet and tone up for the next step in your life. Putting yourself out there will help you out there.
It's been over a decade since I had anything more serious than a fling. For the most part, I don't want to be noticed, it's not that I want to remain single for the rest of my life, I just can't justify starting a relationship with someone else when I still don't have my own life together.
