I voted for having low self esteem. But the inevitable embarrassing moments that happen every single time I venture out in public comes a very close second, and the loneliness/lack of fun a close third. I think it all goes back to my self esteem. I feel so bad about myself that I now feel separate from myself, like I just abandoned myself somewhere along the way, and I barely know who I am anymore. I've lost myself. I miss having my own friendship and feeling peace with my own company. Many years ago I felt OK in myself, and I had fun even if I was alone. Now... I suffer from depersonalisation. That's the worst thing, hating myself for those embarrassing moments, more and more as I collect embarrassing moments, and feeling lonely with my own company, because I don't even have myself. I walked away from myself in shame. I'm realising that that is my biggest problem now.
