Hi Nilanol and welcome
I can totally relate to how you feel because my thought patterns are pretty much the same and I struggle with health anxiety.
I had a cherry angioma on my scalp and when I searched what it was a long time ago I read that it was really a harmless thing. From many sources on the internet. Then one day when I was having a haircut the hairdresser accidentally got rid of it for me
So since you have it for two years now and it didn't get worse, I think you really don't need to focus on that much. If you are not scared of having blood works done, then you can simply ask your Dr to check on the things you are worried about
. They will give you some answers at least, better than googling it I promise.
Distract yourself meanwhile, try to stay in the now.
