Body Dysmorphia

Since the cancer treatment I cant stand the way its made my body look or feels. Its vain in the extreme but I cant help think that before I got diagnosed last November for once in my life I actually looked quite good with my clothes off. Now because of all the time I was so inactive I put on a whole lot of weight. I'm struggling to work it off because my stamina is still really shitty. It fucks me off and makes me feel like its even less likely that anyone is going to find me attractive enough to date.
