post break-up confusion

I’d been dating my now recent ex for almost a year. I hate to admit it, but I changed myself for him, and now I don’t really know who I am. I already suffer from crippling depression (not like the iDubbbz kind) and anxiety, so an identity crisis is extremely overwhelming. I find aspects of my personality and appearance that I hate, but I can’t change or more realistically, I’m too scared to change. I don’t love who I am, I really never have. I feel lost. I’m scared.
