Really hate the way I look.😞 What do you guys think?

I'm usually pretty positive about how I look but two or so weeks ago my boyfriend and I were talking about how our kids would be if we had them and he was talking about how their weight would possibly be as they grow up cause he's a little bit of a big guy and then he said that I'm kind of big too but he didn't mean it in a rude way like calling me fat and he said he meant to say curvy but it still hurt me a little bit though and has made me self conscious again about myself and I just wish I could feel beautiful in my own skin all the time and I wish I didn't have a tummy and stuff, ugh.😞
