See others' advice on seeking professional help.

In my opinion, don't put too much effort into schooling if you want to code. Learn and build. Join a startup if you want to learn to touch a bit of everything, or build your own project if you want to learn to fail and still progress.

Also, what I can say from my experience, is that people that I know that felt lost and depressed around your age are the most interesting people I know today. They're still lost, in the sense that they haven't figured out what they want to be when they grow up (even though they're 40+). They just learned to use and channel their energy and creativity and turn it into positive for them and those around them.
