emotional detachment

Veronica
Hey ladies, I'm seeking desperate advice..
I'm having problems with general intimacy.
I feel so detached...
I've been hurt so many times in the past so many years that I can't bring myself to genuinely like someone anymore lately...almost as though I'm scared to like someone. 
Kissing and sex mean nothing to me anymore, though I want it to, but the idea of getting close to someone freaks me out.
I feel empty inside and I don't know what to do anymore?!
I just got home from a date, my 5th date within a fortnight with 5 different guys, and I actually cried on the drive home because I can't feel anything for any of them.
Can anyone help me with advice or similar situations of how they have overcome this?
