No harsh advice please...

My last relationship made me really insecure about my appearance & personality. I now have another boyfriend which he has been so sweet & patient since the very start. One of his ex's like a year ago txted him because she needed him since she was pregnant & was thinking on getting an abortion & he just told her to think about it right & so & so. Around new years she msged him & he told her to leave him alone that he didn't care about her anymore that he now has a girlfriend which he's happy with & doesn't need anyone else. & that was the end to it. I have GAD & it's hard on me, i feel like he doesn't deserve to deal with me & the problems that i have because of GAD but he says that my hell is his hell. I think i made it worse by creating a fake snapchat & adding that one ex on there to "uplift" my appearance confidence but i see her going out & having fun & it makes me feel like he should be with me, like that will make him happier & not have him tied down to only the things i can do. I was fine & everything until recently my anxiety started getting the best of me again BAD, it's even hard for me to eat. I can't really go to the mall with him without feeling afraid before even going, i feel so powerless that i think im becoming depressed too. Any advice helps since my mind is full of knots after knots.
