Hey, I am 16 years old as well and I have been dealing with the same problem for the past year, except for me, I always smell like feces. Just last week I went to the therapist to help settle out my issues. My mom was the same way with me, but she works for Loyola Medical Center so testing is free.
Anyway, I was prescribed lexapro, which is an antidepressant and I have felt a lot less depressed about my situation. I gave a urine sample and had my blood drawn later that day to see if there were any abnormalities in my body before I started taking the medicine. I haven't gotten the results yet, but I have already taken the medicine so hopefully I will be Ok. I will find out to see if I have TMAU by Wednesday so I will keep you updated.
