Your skin problems are most certainly Adderall related. I haven't heard of the peach fuzz Adderall side-effect but what else can it be? Adderall occasionally turns me into a teen by putting a zit on my face. I'm 57. Hair was there before the zits my case. That's a good thing.
The mood problems are likely Adderall related but be careful about placing hasty blame. Other unseen factors may be at work coincidentally. Many times in my work and in life some unnoticed event took place at about the same time as my "obvious" cause event. Any other possibilities be causing the mood problem?
I don't know the Adderall effect on hormone specifics. Excessive stress from many sources can affect hormones which in turn affects mood. Back to the many possibilities here.
"How can I solve the problem without giving up all the Adderall benefits" is so common. I think all of us playing the game for awhile bump our heads into that wall more than once.
Try to carefully list all the possible causes and then go from there.
