Anyone scared they are going to have an allergic reaction even though they never had one before?

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?

This is going to sound so silly, but I’ve always wanted to try lip plumping glosses, just for fun! I love playing w makeup. Now the issue: I’m scared of the potential burning/tingling sensation. I deal with allergies and swelling lips was something I experienced as a kid during some of my more…traumatic reactions. I have big health OCD around allergies so I’m just scared of putting on the gloss and seeing my lips swell up bc of an allergy and maybe triggering a more serious reaction if it gets in my mouth. Idk how to deal with this…🥲 I could just,,, not wear them, but I also think I should choose that out of a personal choice and NOT bc of fear, you know?

I know this may sound strange and this is no way meant to say people with autism are lesser or anything like that, but similarly to how i fear being gay even though I'm not homophobic and have no problem with gay people, I have a fear of being autistic. Everytime I see a list of autism symptoms online or a post on social media that's like if you do x you must be autistic I literally panic. I'm constantly monitoring my behaviour in case I show any signs and I'm always looking at old photos and videos of myself for the same reason. It's also annoying that I have a bad memory so I can't really rember if I did something in the past that definitely means I have autism. My brain keeps focusing on moments that could mean I have autism. Like if I misunderstood a joke one time in the past my brain keeps telling me that's a sign I didn't understand a social cue so I must have autism, even though there are probably countless times I have been fine with social cues, its just I can't remember. I have also had a time in the past where a therapist brought up I could potentially look into seeing If I have autism, but I just keep telling myself she said potentially and she only brought it up because of one potential sign and not a whole list of signs. My only reassurance is that I've never had anyone mention any autistic like behaviour to me or my parents when I was little and I keep asking my family if I showed any particular signs of autism and they keep saying no, but knowing my family they wouldn't have noticed even if I did. I just feel so scared and so guilty. There is nothing wrong with having autism just as there is nothing wrong with being gay, it's just so scary to me though, I really dont want to have autism and don't know why I just don't. Does anyone else feel the same?
