Relationship/social skills/interpersonal skills problems, any books/resources I can use to help with this?

hello, I've been really stuggling in this area due to alot of trauma. I can't even get friends. my family abandoned me, and I've been completely alone for years even. I can't talk to no one and its been really hard. My depression is getting worse to the point I'm thinking of killing myself. if there's a resource you can recommend or a book that can help with this area id really appreciate it.
