Struggling with Health Issues and Weight Stigma

Hi um.. I'm not great at really wording things well, but there's just so many issues with my body and I don't really know where to start on anything. The two doctors I've had in my life haven't helped much since they only focus on my weight. I'm not a healthy person, I can admit that, but there's just so many health issues getting in the way of making things better mentally and physically that I'm overwhelmed with getting diagnosis' for anything. None of the things I've put on my profile are diagnosed but they feel so obvious to me that I had to. I don't know how to approach therapy or physical health help because I'm too scared it'll only focus on my weight when there's just so much stuff that's a factor to it. Sorry that this is so long
