Super anxious today. I’m scared to even write out why.

I woke up feel so anxious right now again, how to help that feeling?

I'm going to try and be coherent because I know that sometimes during these moments I tend to babble in fear. I have a mole on the left side of my chest that I've had since I was a kid. Been there for as long as I remember. And I never paid attention to it; it was just a part of my body. I even felt a little sad considering that I might not have it anymore whenever I get top surgery. Yesterday I went down a rabbit hole and landed on Melanoma. Which, of course, prompted me to look at my mole again. And again. And again. It's large, bigger than my other moles. Always has been, at least to my knowledge. I always thought it was cute whenever it crossed my mind. Now...now I'm just scared... I'm not asking for reassurance. None of us on here are medical experts (unless youre an actual doctor) (also insert OCD joke here). I sent a picture to my doctor, and she said that if it hasnt changed size that's a good sign. But she also suggested a follow-up with a dermatologist. And that's what scares me the most. All of this started yesterday, but I sent the message to my doctor this morning. And ever since then...I havent been okay. I can barely eat, and every time I try to I can barely swallow. I've isolated myself in the guest bedroom of my parents house. I cant move. I cant think straight. And...let's just say my thoughts havent been good. Like I said, I'm not asking for reassurance or medical advice. I just...I need help to not feel like I'm dying. I didnt mention that yesterday, in the midst of going down the rabbit hole, I realized how badly I didnt want to be afraid, and yet I also felt like I needed to be afraid. And I realized that that's what ERP is (at least for me in case it's different for everyone). I really did naivietely think that it was just going to be about avoiding compulsions. I didnt realize that accepting uncertainty would feel like a death sentence. And now this has happened. I just...I'm scared. And I dont want to be. I dont want to live in this reality where I'm sick and dying. I dont want to have to tell my family. I dont want to live in that world, but it feels like I'm already in it. My body is just preparing me for it. I dont know. I dont know why I'm even making this post. No one can help me, can they?

Can someone help me? I was trying to clean my daughter’s car got hot and got anxiety now all I can focus on is my heart rate and it doesn’t feel good and I am freaking the f out!
