My suggestions ...
(1) Church. Find one with a lot of events to keep you busy. Church is free, and full of good people who will keep you company and help you out. At the very least ... they meet once a week. If you get into a Bible study class, you’re looking at another time-or-two a week.
(2) Find a way to serve someone else. You will be surprised at how much helping others can relieve depression.
(3) As for money problems ... stop focusing on what you can’t do, and find out what you can do. People often defeat themselves with “can’t” before they even start. It is better to try and fail than to simply say you “can’t”.
Godspeed.

Double down on every point that SnakeDoc made. He has it nailed to the wall.
To add point 4 to Doc’s list:
4. You must do exactly, to the letter, as your doctor says, meds and all. The medications that you are taking are probably very good but you have to take them consistently.
I spent most of my life thinking that I couldn’t do things but after spending a few years in a good church I found that many had done those things. I started acting with a great deal more confidence and it changed my life 180 degrees. Hard to even describe the change. From introvert to extrovert would be a good start, but it goes deeper than that.
Church is the key. Love of Jesus and His Father is the Way.
Good luck.
