/cgl/ - Cosplay & EGL

Help, /cgl/
I'm 90-76-100 and I've had body issues all my life. I know I'm not landwhale huge but I'm definitely fat compared to all these tiny girls I see on cgl and tumblr.
The problem is, I've been curvy and had puppy fat my whole life and it's never changed whether I eat super healthy or if I eat tons of junk food. It doesn't help that I live with family who keep buying junk.
I have diagnosed hypermobility, so I can't do any hard workouts either. It's like I'm destined to be a chubby-chan forever and it makes me want to die.
Is there any way I can fix this?
