Oh gosh, I'm so sorry I kind of know how you feel

These three:
"2) I have no one to love me
3) I'm unattractive to men
4) I have no one to hold me and comfort me"

Really hit home. It sucks when you see so many happy people around you and you feel like you're drowning in loneliness.

I really wish I had more advice to give you, but I'm in the same boat.

All I can say is stay strong, don't let anything pull you down, you can do this. Keep your head above water and pretty soon you'll be swimming with the current as opposed to drowning in it.
