Asexuality, hypothyroidism, and PTSD
The only reason they found out that I have hypothyroidism at all is because I decided to try some medication for PTSD, so they screened me for it. PTSD shares some of the same symptoms—poor memory and concentration, depression, and fatigue (from PTSD affecting the quality of sleep). Some of my other symptoms could have been explained by other factors, too. So I think it went undiagnosed for a long time.
