Hey, I can understand your state of mind as I was in the same place a few months ago.

What you are doing is good, keep it up. I would suggest, do try some activities that you can do by yourself, photography, reading, just sitting on the roof and looking at the stars, trees, birds etc. Learn to enjoy your own company, slowly you will understand what makes you anxious and you yourself will learn to deal with it without any medications, drugs or alcohol. Also it is helpful to have one person you can talk to, but not necessary.

Success is subjective, try to make yourself capable enough to earn as much money as it is needed to suffice for your needs, which I guess are already pretty minimal.
