Body issues


So I know everyone has some sort of insecurity concerning their body. And I’m also aware that to most people I am skinny but I have severe issues thinking that the slightest bit of fat on my body will make me undesirable to my man. It’s consuming and I hate that I think this way. my boyfriend is constantly telling me I’m perfect but I’m so annoyingly paranoid that if I get chubby he’ll leave. As well as I feel like I’m not “thick” in my booty and boobs

and idk why I worry about it so much. Any advice on how to calm my nerves and love my body??
