I want to start losing weight but can't get myself to the gym.

Hello all, I am wanting to start losing weight and am really struggling with how I'm going to start. For some clarifying details I am about 250lbs and 5'8. I know am very overweight that doesn't have to be stressed to me. I am also trans masc and use he/him but I am afab. Im really struggling on the getting the energy to go to the gym and I also know that there is no way Ill have the willpower to keep it going after a day, I am no where near fit and struggle going up a flight of stairs let alone a full workout, Im also doing this alone, I have no support from friends or family cuz I don't talk to my friends about this and my family just wants me to take Ozempic but I refuse. I'm think maybe I can start with swimming cuz I love to swim but I struggle putting on a swimsuit and going out in public thanks to my dysphoria. Idk y'all I'm getting really close to cracking to taking Ozempic but I don't want to accidentally spark an eating disorder as I have a higher risk as well as having an already poor relationship with food (obviously).
