For a teenager is this normal?

Hey I'm currently a bit confused. I'm a teenager and have been wondering if I may be just very burnt out and hormonal or if I am possibly depressed.

I am constantly run down, tired and have migraines/ headaches. I also have possible adhd and I have questioned my sexuality multiple times.

I always get very strong surges of anger and lash out at every thing that annoys me, then I have also tried to self harm a few times but then not having the guts to do anything major

Finally I have felt very emotionless after my outbursts and have thoughts on suicide or doing things like jumping out my window etc..

Anyway I was mostly wondering is this in the realms of ok and normal and what to do about it.
