I was feeling exactly like that a while ago, especially with the constant loneliness and co-dependency on me by others. Understandable.
I can't tell you how to fix your friendships, that's up to you. Albeit I can tell you what I did on my own. The biggest thing to creating healthy friendships for me is to find something you can do and talk about with them together regularly. It doesn't have to be as big as a shared hobby, a shared routine activity is enough. This allows you to open interactions on a tone that doesn't touch your or their emotions.
It might be obvious, but don't go around telling your friends about your worries if you do not want them to do the same to you. They might be fed up with your self-deprecating talk and will pour their emotions on you instead.
TL;DR: Find topics you can circle your conversations around, write down some conversation starters to use and try to derail any self-deprecating rants while respecting their needs (aka do not be that guy who is mean to sensitive people for no reason.)
