I am right there with you, in my thirties, no kids, no family, no house....this HURTS terribly......the LACK of good things is just as painful as the PRESENCE of bad things, it seems...
My church helps me, my friends, (good and true deep friends

) My support group..these are some things that ease my pain just a BIT,,,
I used to get mad jealous whenever I saw a happy couple,,and that was quite a bit- they are everywhere!!!!!!!!!
It;s like you can run and hide but couples (and families..) seem to pop everywhere, reminding you of something that you just dont have and cannot even WORK to have...it is all a matter of damn luck grrrrrrr
Your presence on PC is a good one,,that is another outlet you can nurture, when you feel up to it..
Just wanted to say, I HEAR YOU

I validate your feelings..for they are deeply mine also
