I don't think it's the right way for you to force yourself to exercise now, because your heart rejects it. I suggest you take your time now and start with more stable sports, such as running and swimming. If you are happy in it, you can continue to try and find your own interests. Exercise is not only a process of exercising the human body, but also a process of exercising the will and making friends. Its benefits are unimaginable, so now you have to instill a belief that you can. If a friend asks you out to exercise again, you might as well agree and experience it. Even if you look carefully, you will feel happy. Perhaps it is the tacit understanding between friends, or the appearance of sweating, or a casual joke, and a ridicule will change you invisibly. Take your time, I believe you can succeed, because you are the best ~ Come on!
