Bloating or just a lil chubby?

I'm sad because I'm going to the lake with a bunch of people and I don't feel or look good in any swimwear but I want to wear a suit not a t shirt.. Now I'm not fat I just have a little pooch and I hate it and I'm not as skinny as my other friends and it's just really hard to lose weight and I get overlooked by guys, and so now I'm thinking to avoid the embarrassment and awkwardness, I don't think I want to go anymore even though I want to have fun, but my anxiety won't let me! ☹️
