Help How do i stop my brain going into freak out mode whenever the concept of someone leaving/blocking/etc someone else is mentioned?

[coolgal82]

My brain is like really sensitive and idfk why, like if someone just mentions breaking up with or cutting contact with or blocking someone or anything like that, or even if something someone says just makes me think about it (and even other unrelated things like any mention of people being generally weird in a negative context) and go "hmm but what if that happened to me what if someone i liked blocked me" and then it spirals into like "oh god it's gonna happen eventually" and "everyone actually secretly hates me because im weird" and etc. I could literally be feeling fine snd chilling then one mention of it makes me spiral like that and i usually end up like turning to unhealthy mechanisms to like stop it from spiralling further.

How do i like stop my brain from doing this?
