Experiencing Severe Fatigue, Do not know why

[mymicsoundsgoodcheck1]

For the past few years I have struggled with mild fatigue, which I believe at the time was caused by stress/anxiety I put on myself. However, for the past 5 or 6 months my fatigue has gotten much worse and I am not sure why. Fatigue is the main symptom I have, but other symptoms include black eye floaters, somewhat sensitive to bright sunlight, dizziness upon standing after lying or sitting, constant yawning, I force myself to workout even though I am usually much too tired, poor concentration, and a lot of the time I can feel the exhaustion in the front/top part of my head. I do not have any problems falling asleep but wake up every morning feeling as though I've been hit by a bus and got no sleep the night before. I also do not have any problems with diarrhea or vomiting, however for about 3 months last summer I had on and off stomach pain that I took Prilosec for that eventually just disappeared. In addition, it seems as though the worse I feel the lower my sex drive is and I sometimes get acne, but I am not sure why sometimes I feel noticeably worse than other times. I eat healthy, workout, get enough sleep, drink enough water, etc. I have had physicals and blood tests done, have had my heart checked and x-rayed, etc, but everything came back negative. I have minimal stress and anxiety now, but feel even worse than I did a year ago. I've been doing my own research online but am still not sure what could be causing this. I am a 21 year old male.

Have you had your testosterone levels checked? A lot of the symptoms you describe are symptoms of low testosterone. I had a lot of the same symptoms you do about 2 years ago. They tested my testosterone and it was lower than an 80 year old (I was 30 at the time). Also have you had your thyroid checked? I think Hypothyroidism could cause some of those symptoms. Lastly, do you take any medications like SSRIs or anything? Those can give you some of the same symptoms. If you do talk to a doctor about testosterone you may have to push to get them to check it and if you are low you may have to push to get treatment. I know I did.

Yes, I had them checked. They are definitely on the lower end, but still within the range. I am meeting with my doctor next week to go over other possibilities including testosterone, thyroid, cortisol, sleep disorders, among others.
No, I do not take any medications
