I understand how u feel cause i have problems in meeting or even trusting a new people especially girls.. because im just afraid to get hurts once again (ive been dump by my ex 6 times in a row and 3 of them are cheating on me, the recent one is the hardest one cause we were engaged and shes cheating on me 2 times, the last one when she dump me, shes cheating with more than just one guy) so now it leaves me with no other choice than closing my self and build a shield to prevent me from getting hurts anymore.. but i realise i cant stay alone.. so maybe u could try what im trying to be friended with someone over the net as a start to at least open up my self abit and to train my self to have abit self confidence, but thats not easy as well for me cause no one wants to be my friend.
