How did you get over being the most over weight and weakest guy at the gym.

I broke my ankle 4 months ago, and now knew that I'm over weight with 20 KG of fat and I need to heal through physiotherapy at the same time, so I'm seeing a doctor at the gym.
I have to stay for more than 3 hours cause my case is more of practicing, I also have to treat my ankle, so I spend lots of time seeing lots other guys and girls, even older people. I noticed that I'm one of the worst bodies around, I'm obese, weak and inexperienced.
Most of the guys have really better bodies and looks than me, I look in the mirror and I see myself as a short fat person who also happend to sprain his ankle badly.
I'm also the weakest of all. I look like I'm dying while training my abs or cycling while other guys are chill and really look like those trainers on YouTube. Even girls and older women can carry more weights than me. I also feel that I'm not doing the training the right way all the time and I'm constantly doubting myself.
Did anyone had this feeling and thoughts before? And how did you get over it?
