Okay so I know Ive been interacting and talking about stuff regarding it a bunch recently but (pic unrelated)

I think I just WANNA be a chubby girl. I don't know how I could let this make sense, but I'm just so jealous of them. I've never been insecure before but recently I started to get really uncomfortable with how thin I think I look, and all I want is to be chubby. Along with that comes that it's definitely not my first time being jealous as fuck of how pretty girls are naturally, I love the usual soft long hair, the face, their... You know.. everything? My personality is already a little feminine so I won't mention that but God I just... Wanna be a chubby girl :( What the hell should I do if anything???????
