no social life

I don't have a social life, at all. Not even one person to text when I'm bored. I'm 18 & its becoming VERY unhealthy. I already suffer from depression. I'm on meds, been in a mental hospital, go to therapy but nothing helps. I feel like if I had a social life like a normal teen I'll be ok. But I have a baby. I want to go to college & live on campus because I think that'll help a lot but then again Ive been thinking of getting an apartment for me & my baby to have our own space. Then I had another break down & noticed me living alone could be dangerous. I've already attempted suicide once. What do u think I should do? Try to be a normal teen @ college or just become an adult (get an apartment & work) idk why but this is so hard for me to decide on
