How do i make friends over again?

This may sound so retarted but i dont know who else to ask. I am 24 and used to have alot of friends in school. I met a guy when i was about 17 and married him when i was 21, he was abusive, and in return throughout the 7 yrs with him, i feel into a huge depression, and lost most friends, i have one left who was my best friend, and we talk sometimes. I have been in this same town all my life, all my friends are starting to come back to town that i had from school. The problem is i lost touch with them all and we grew apart, but there is this website i found them all on, and im really scared to talk to them, they know im on there and dont really make a attempt to talk to me. I really miss having a group of friends, and im scared they outgrew me and they dont want nothing too do with me now. They all still talk but im out of the pic, i miss friends and i dont know how to rekindle with them all.....im really upset about this so any advice, suggestions would be great,
