Having trouble picturing life

I’m new to this community, but I thought I’d come on here for some advice and to share my thoughts. I 26F have a very strong sense that I have cushings. I have the Buffalo hump on my neck, purpleish stretch marks on my upper arms, the weight in my mid section and skinner arms and legs, my hair has begun to noticeably thin out and random cystic acne, one at a time every couple weeks for the last year, which has never happened to me before. Mentally I’d say the last 2-3 years I’ve felt my personality slowly change. I feel regularly like I’m about to have some sort of panic attack, Im depressed often, and always have a tinge of anxiety running in the back of my mind, even on good days. I have not begun the journey of doctors appointments and getting diagnosed yet, I plan on starting that process in about 6 months. But my main fear is will I die? I don’t want to be dramatic at all, but I’m so scared. I try not to google too much but the internet says untreated cushings can take your life In 4-5 years what does this mean? If I get diagnosed and get surgery will I confidently be okay and be able to live a normal life? I feel this sense of dread and doom that something really bad is gonna happen or this disease will take me if I really do have it. This could be my anxiety talking but I’m just not sure what to make of this. The thinning hair seems to be really freaking me out I think it’s making me associate this with cancer if that makes sense? I don’t want to get ahead of myself but I’m just unsure and afraid of what the future might look like if I have cushings.
