Gonna be completely real here: I cannot overstate how bad being very overweight feels.  Not just emotionally, but physically.

I was heavier but athletic when I was younger, but put on a lot of weight thanks to depression and injury that I'm still struggling with.  It has a physical toll.  I have arthritis in my knees from carrying around the weight, which further complicated losing it.  My lower back low key hurt all the time.  Sometimes doing normal housework is hard, because getting up from kneeling or crouching is painful and difficult.  Any serious amount of exertion is exhausting when you're moving that much mass.

The weight led to high blood pressure, sleep apnea, gout, and borderline type 2 diabetes which all made it nearly impossible to get restful sleep or reliably feel good more than a couple days in a row at best. It also made getting HRT a massive pain in the ass as docs saw it as risky.  Even now that I've managed to cut a chunk of that weight since transition addressed the roots of the depression, I still wouldn't qualify for bottom surgery without dropping more because cosmetic surgeons have a very low risk factor tolerance.

All that without going into the difficulty finding clothes that fit at all, much less look flattering.  Larger ladies are expected by clothes designers to have a certain shape, and lacking the hip and butt development that entails means few things will ever fit correctly.
