I'm not quite twice your age, but I've had this off and on as far as I can remember. Keep trying new things, finding new music, engaging with new ideas, and maybe try low-risk recreational drugs like weed and hallucinogens (I recommend staying away from uppers and opioids as they're very addictive).

I don't want to imply that drugs are a good solution for everyone or a silver bullet, but if the problem is in your brain it might help rewire it in a helpful way. Be aware that you need a healthy, supportive environment for that. Accidentally taking too much LSD really helped me see things differently and killed my depression for a year, although it did come back. Now, a friend of mine had a similar experience but had a negative outcome, so it doesn't work for everyone. But, I've been so much more open to new things since. Hell, I'll sing and dance in public now, something that would have terrified me at your age.

I guess this is a rambling way to say it will get better if you put in the effort.
