Hi sophie!! I can't be a swimming buddy but I am 1000% right there with you. I'm 28, lonely, I've got multiple health limitations, and feel like each day gets lower. Just think of this post as taking that positive step into getting better. You can, there's no reason you can't (despite all the hormones or injury or whatever ,you CAN. I promise).
I won't bombard you with empty optimism. This is going to be hard but you did the right thing by coming to a place with support to get yourself on track. If you need a chatting buddy do not hesitate to shoot out a message
Lastly, you could be 700lbs and still have zero reason to be ashamed going to the pool. you should never ever be ashamed for doing something you love or for trying to better yourself, no matter what your size. you can't change how the world is going to look at you but for now you can at least change how you look at yourself.
