38 year old male with low sex drive?

I was diagnosed with hypothyroidism 3 yrs ago and hav since been on synthroid 200mcgs everyday. My sex drive was still low so i went to urologist and he checked my testosterone levels which were normal. I also ruled out my blood pressure med as a possible culprit(i quit taking for a month) and it wasnt the issue. Now im thinking about asking for armour thyroid cause i heard it can help. What else could be affecting my sex drive? I eat good exercise 5 times a week and dont smoke, only drink on saturday. im also feelin fatigued and not a lot of motivation. if it werent for me pushing myself at the gym i would have no energy whatsoever!! I cant date because ofthi condition. I also have erectile dysfunction too. I am so angry at my body. i was never like this when i was younger. please help me if you could. 10 pts.. thansk..
