I think you need to seriously reconsider your actions. To be without sex hormones at 19 is to risk rapid bone loss and probably osteoporosis and deformity (think of those old women you see who look like hunchbacks; this is due to their fragile vertebrae cracking then healing time after time after time.) You will lose breast tone and some of your feminine body shape, though you won't return to your "male" status due to having had surgery. You are also likely to suffer from hair loss, sweating, rashes, trouble sleeping, dry skin, headache, and possible emotional issues. There was a time I had to go off hormones when post-orchiectomy to see if it helped my migraines, and I felt so horrible I can't imagine ever going back to that. April Ashley, in her book, discusses having gone off HRT after surgery due to bad medical advice of that period, and she ended up with multiple bone breaks and a heart attack.
I don't know what was wrong with your "mental state" that you thought "life threatening" complications was worth going off HRT, but I strongly suggest you make an appointment with a psychiatrist or other mental health professional in addition to the one you have with your endo. I don't know what HRT you were taking, but for most people plain old estradiol has few side effects and certainly nothing worth risking your life over by stopping. You are very young, and the risks of stopping HRT are much higher than for a woman who stopped, say, in her 50s or something.
