Tired of feeling tired. Hormones could be the case?

I'm constantly tired, I feel mentally exhausted most of the times. Can't think straight. weightlifting (pretty heavy) could be harming me more than even getting me to a healthy level. I wonder if maybe it could be my weight? 152 at 6'2. or stress and anxiety? I do have depression and OCD, but I also have low levels of testosterones total and free. I have went to several doctors to check my testostone and can't find a reason.

maybe it's because I eat very late at night? I eat around 11:30 pm and go to sleep at around 2. I wake up like twice to go to the bathroom during the night.

Idk what to do and need help. Doctors for my hormones are not getting anything solved unless I inject myself with testosterone I guess.

TOTAL cortisol am is 18

 

Eating before 8 pm is good. Eating too late makes it harder to digest.
