Problems with weight.

To begin with, I don't speak English (I'm Brazilian), so the post may be a little confusing. Anyway, I'm a woman (19 years old) and I've had diabetes for 7 years and I've never been able to maintain a stable weight. I've been overweight since childhood and only got worse after the diagnosis, my doctor always complained about my weight and highlighted that IT WAS A PROBLEM, and now that I use contraception it's only gotten worse. The only time I was at the "ideal" weight was when I discovered diabetes and almost died, I went from 62kg to 50kg in a week, and I was around 50kg until I was 1 year after diagnosis, and everything went wrong during the pandemic, since then I've always fluctuated between 70 and 80kg, no more and no less. I did yoga for a while, I know it's not something that has a big impact, but I have an undiagnosed problem with my hip, as well as being a kind of therapy and being associated with a diet, but it only worked to make me more leggy (I'm naturally lame, being overweight only highlights this). Furthermore, I tried and managed to "induce" ketoacidosis a few times to lose weight quickly, it worked but it wasn't worth it, I was left with a pale complexion, insatiable hunger and mortal thirst, in addition to absurdly high blood sugar levels. I did this stupid thing for events where I wanted to look beautiful, but I risked my life to do so. Finally, I wanted to say that it's just a rant, it's great to find a community that suffers from the same problem, I read some posts and I imagine that most people here are from the USA. I'm learning English, but I'm still too insecure to write or speak, so I hope it won't be difficult to understand what I wrote.
