How often to shower and how??

Please no judgement...okay I'll explain a little better. I have a tracheostemy due to tracheal stenosis. Basically january of 2015, I tried to kill myself by overdosing on pills. Before i am judged on that, i was at a point in my life that I hated myself. I cut myself. I cried everyday. I stopped caring. I was abused and ignored alot of my life. I was raped at 16. Before my fiance, i hadnf been hugged or touched by another human in a loving way since age 12. I was last on everyone's list. All through school i was made fun of, ignored, called names, had things thrown at me, no friends, being used all the time. I felt worthless and like i was burden and i deserved to die. I am people pleaser. Enough people told me i should die for years. I finally couldnt hold on any longer...when people drive you to a point of feeling like death is the only way to be happy theres a problem. Theres so much more i can say but your just strangers...Please dont hate on me... im still trying to recover. I started seeing a psychiatrist and I have bipolar disorder, depression, anxiety, borderline personality disorder. Anyway, my fiance called 911 when I started hallucinating due to the overdose and was screaming for him. I was in the shower and he didn't know what I did. Well I was intubated for 10 days in a coma, not knowing if I would make it. Afterwards I developed the stenosis due to the ventilator. Well I have been in and out of the hospital a minimum of once a month since then and sometimes more. I have been in medically induced comas 6 times since January of 2015. I am fat. I haven't been able to exercise because I can't breathe. They put in the trach so I always have an open airway and my throat will stop closing up. I have to lose weight to be able to have open chest tracheal reconstruction surgery. I have to get to at least 200 pounds... so because of my breathing, I can't walk more than 10 minutes because I feel like I'm suffocating and my oxygen drops to high 80's. Since I am fat too thay makes it harder. So I need to break it up. I have always sweated alot. So I'll be almost drenched after that ten minutes. I feel really tired after walking just that so I have to aait hours to build up enough strength to do it again. I am on disability right now trying to get all this healed and on with my life. I am only 20... I have hidradenitis, a skin condition, and if I don't keep my skin clean and free of sweat and dirt, it will flare up badly then I won't be able to walk at all and it could get infected. Plus, If I go out in public in between my walks for whatever reason let it be a doctor appt, the library, a store, etc. I don't want to smell bad. People already stare at me and judge me for being fat and having a trach. I just wanted to know what other people do on showering and sweating alot... thank you.
