I no longer feel beautiful

My boyfriend left me a few days ago and I kept asking him why and to tell me the truth. Well he gave me the truth and I spent all night crying wishing I could disappear. I’m bigger and I started to love myself because last year I was 325 and now I’m 278 and I’m still struggling to try to lose weight but now I feel like shit n I can’t stop crying. I no longer feel sexy and I came here in hopes maybe y’all can make me feel better. I know it’s a long shot tho.
