how do I leave my apartment? [25 F]

someone please talk to me. highschool and employment of the past just burnt me the fuck out i guess. (aside from just being disabled lmao) I'm overweight. I have no pet. I isolate myself. The walk to the train feels extremely distant. I hate the sound of cars that I have to pass to get there (I'm really sensitive to sound, like get anxiety attacks really easily). I hate being around people because of my OCD, GAD, and being transsex but not done transitioning. I need to hit the gym or something to get into shape. I need to get into a dnd group for socialization. I need to actually continue my transition. It just feels unsafe, and it takes so much effort. ugh. idk I've been doing 'better' lately, in that I've been cooking like twice a week, and i keep my apartment kind of clean. I guess I want advice or something, because I'm so scared / depressed when it comes to the world outside. Oh, I also pass as female now, so I guess going out at night is now more dangerous, which sucks because the night is more appealing to my autism or whatever I have. Low light, low noise, low temperature.
