Im not sure if this is scoliosis, I think I remember a doctor telling me its not. My spine kinda "sticks out", you could see it through my shirt if I bend over a bit. I dont gets much back pains. Anyone have any idea what this is? Its been like this as far as I remember...

You asked this question many times before on these forums. Take the advice you were given. Teenagers often experience anxiety and depression.
I suggest seeing a counselor, see if your school offers one. Talk to your parents about this.

Have you been feeling depressed?
Since its been going on for so long, its most likely your health. Anyways, just ask your doctor, you should get some blood work done.
