After a few months of feeling unreasonable sad and low-energy and losing weight, I went to my doctor and got a bunch of blood tests done. The results came back that my testoserone was lower than in the past. I felt relieved to see that there might be a reason why I was feeling so down. (I went back and got retested a few weeks later and my levels were normal though. So not sure what that was all about. lol)
