Some things to think about

We have very little control over how our bodies look
How much you weigh is honestly pretty boring, and the world is full of so many more interesting things to think about
If you do gain weight, so what?
You have no obligation to be attractive
Physical health can be extremely complex & difficult to manage, and whether or not you can is not a measure of your worth.
Mental health is important too.
You are worth so much more than the way you look.

Think about this and then give your mind and energies to more worthy ideas..
