This article is well written and provides excellent insights on the feelings of a person who doesn’t fit the norm in the current standard of “beauty”.
It also potraits the corresponding behavior pretty well, which induces the scaring expectations.
My point here is:
Why is being “fat” described as a characteristic that is unchangeable? No matter what your genetics force you to look like, no matter what your environment and friends seduce you to do, you are the author of your own life. We are fortune enough to consume knowledge everywhere. Why not use it to shape your body? Especially if it has such impacts on your life? It is 2017 you can do everything you set your mind to — go for it!
And ultimately, as you reflected correctly: It is not the looks that matters. Having fun and feeling comfortable is what attracts people. You are the person you think you are. It might not always be easy, but the one that doesn’t try has already lost.
Keep going :)
