I feel the same way about your sig - it summarizes my whole people issue perfectly.It felt like i was looking into the mirror when i read your post...
I am in my late 30s, but when i see even children handling people with complete ease, then it makes me feel like a completely pathetic human being. Failure in just 1 or 2 areas, such as looks & social, seems to take away a big chunk of general self-esteem & confidence. Society knows this (hence the personal attacks), and i'm starting to accept it as the truth. No matter what else i do, failing in just these 2 areas destines me for a life of heartache. Sad but true, it seems.
