Do I have adrenal gland problems? Pls help. Kinda scared?

I noticed symptoms such as fatigue, wasting of arms if I don't eat enough, bad memory, high stress, high blood pressure. This started ever since I started lifting weights( once I gained a considerable ammount of fat). I used to get good blood flow to muscles, now I don't. I find it hard to sleep at night. I also fall asleep after I workout. I don't want to go the docter cuz I'm scared of what the results will be. What do you guys think? I'm 16 btw. Idk if this could be part of the problem, but I've been take pw supps since age 14. What should I do? I hate going to the docter.
