Help! Do I have an adrenal gland problem? I'm 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
