Seriously, your prospects for a better life are very good if it is true what you're saying. That's not some cheap joke at your expense, but a new way to look at your (new) life. Better accept it as it now is (but never stop trying for stability: your life back, even if it's momentarily!)

You are (probably) gonna fail a lot more often, but after (and towards the end of) each depression you have the chance to regain what you lost. It is not easy, not fun, but it can restore the belief and let you see the strength, in yourself if you try. Slowly but surely you will do better again. The friends you lost probably weren't the best friend material if they don't wait for you at the other end. It really can safe you time that way, finding the best, lifelong friends to spend most time with.

Hope you feel better. Then go for it!
