I'm sorry this has happened to you, it sounds really difficult. From my understanding, it feels like you are living a constant pressure to look a certain way and keep seeing yourself for the worst whenever catching glimpse of your reflection.
As an ugly male, I hate seeing myself in images (haven't had any taken for years), and mirrors (now removed where I can).
It may be that as a male, I get judged less on my appearance - at least outwardly/openly. I did however have a 10 year relationship with someone I thought was very beautiful, who at least, for a time, I believe may have felt the same about me.
Although I feel hypocrisy in saying this (as I cannot currently muster up the ability to do so), I would like to think that appearance and identity go strongly together. If you are able to form and hold onto a unique identity, others will hopefully associate your appearance with your unique traits, and there will be those that really do think you are beautiful in appearance as well. Perseverance is hard when at your lowest though :(
I just hope someone tells you they sincerely believe you are not ugly (in any way) sooner rather than later.
