Vent away man. So much of what we're all going through all feels the same. Human suffering is a pretty universal experience. I've hated mirrors since my jaws first grew wrong as a teenager. I've avoided them like the plague. I hate even just seeing my reflection in my tinted car windows as I get into my car in the morning.
Many days I try shaving (electric) without looking in the mirror but that never goes well
and I always have to face my reality. SSRIs aren't bad if you tolerate them. Escitalopram is comfortable. I like St. John's Wort better though and that's over the counter. So that's an option as long as you're not on finasteride/dutasteride or other meds since they interact.
If the therapy works, let us know how it goes. I think that at the end of the day if you're ugly, and you can't be less ugly, then you must accept quality sex or female companionship will never be an option to you, and then do what Cap was saying and focus on having the happy moments you can have (listening to a song you love, whatever you can think of in the moment).
I suppose in that respect, if that's what therapy can help to accomplish, then it's worthwhile. Plus dealing with whatever other issues you might have.
