advice? please, i dont know what to do.

this is all going to sound so jumbled up, sorry

i have really bad confidence issues
and it doesnt help that everytime i be nice to someone,
they use to me until their content then dump me and spread rumours about me
i practically have no self esteem and people are always making it worse

my 'friends' are never there for me
and when they actually stopped talking about the bf's and listened to me
all they said was ' you have to go through it' and push me away
just so they dont have to be inconvienced with my troubles
when all ive done is be there for them, night and day.

my counsellor doesnt help much either,
she says that people dont leave me,
they never leave,
that i push them away and block them out
till they have no choice.

i mean, maybe she's right,
maybe i am my own worst enemy

maybe if i had one boyfriend that wouldnt cheat
or one friend that wouldnt dump me
someone i could talk to?
maybe id be different..
