im 27 and i think i am deeply depressed,i dont know why the friends i have known just dont call anymore,i feel so alone.i have never been friendly as a kid coz i was born rich,friends just come to me and i took everyone for granted now i am left with nothing and no knowledge to make friends since i never learned how to make friends in the first place.i feel so neglected and abandoned.i am severely overweight,no one really cares about me.i feel like my career is eluding me and it makes me very negative in my daily life,why am i still existing?i feel purposeless.
