Could My Low Libido, Concentration Issues, And Fatigue Be Related To Low Testosterone?

Hi, i am 21 years old and have this problem... My libido is very low(i know how i used to feel before, i would get exited from everything, now i have problem keeping an erection sometime because i feel bored during interaction), i have problems concentrating, problems with my short term memory, i feel tired all the time and the only thing that gives me a sense of motivation is fitness and martial arts... i thought it could maybe be a low T problem and got my Testosterone levels checked, 9,2ng/ml... my doctor gave me antidepressants after just a 5 minute talk without actually thinking about it, and i have problems going to another doctor because -a) i feel ashamed b) dont really feel like going in a place where sick people are „gathered“ right now. I would be very thankfull for a response.
