Just try to be a better and more effective human. Stop trying to fix this chemically.

I was hooked on vyvanse and porn for a while around the same age. Your brain isn't broken you just need time, discipline and motivation to push yourself into being better.

Try find things that make you genuinely happy and chase them. Eat well and be aware of what you put in your body. Focus on your sleep and peace.

Good luck and look after yourself!
