Dealing with Anxiety and Magical Thinking

Hi. I’m new on here. I have crazy anxiety and OCD. I mostly deal with magical thinking which causes a spiral that I can’t get out of. I find something, usually involving my health, and hyper focus on it. For example, if I think of something like a friend and then all of the sudden I see them or they call I think I thought it so it happened. Then I will spiral thinking all the bad things I think about I will cause to happen too. Hence magical thinking. I google every health thing imaginative and even though I know I’m being irrational I can’t seem to come out of it and am convinced that when I see an ad or something I have been obsessing over that it’s a sign I have it. Like this app. I have thought I wish there was a place to talk to others about all of this, like a uplift group and poof here it is. WTF. Over it
