I’m too insecure..

Ok so I have never had a boyfriend before, but I feel like part of the reason why is because I’m so uncomfortable with myself. I’m 5’7” but almost 200 pounds so I’m a little thick 😅. I’m super self conscious about my weight so I tend to wear XL clothes even though I fit into Larges... I don’t know how to get comfortable with myself and, to be honest, I kinda gave up this year and I haven’t really been caring at all about my mental/physical health at all. Does anyone have any tips on how to get over being this insecure?

(This is what I look like on a good day lmao)
