i can relate. i've dealt with severe depression (two years) and chronic anxiety (six plus) for a bit, and it's certainly not an easy task to overcome. it led to me trying to overdose which landed me in a rehab facility after it ultimately failed, where i spent about three months.
i did learn a lot of skills to help me cope when the going gets rough, though. not sure if any of these would work, but: i picked up playing the guitar, singing, and drawing as some extracurricular stuff to keep me busy. i'd recommend medication if it seems to work for you or something else if you aren't interested, i.e. art, gaming, etc. but i give you my deepest condolences and can assure you i've never been happier to be alive than i am right now. i hope you can work through it, man.
