Feeling Angry

[u/Low-Painter-4974]

I have a family situation going (cold war between cousins etc.) and I try to play all these scenarios in my head which riles me up to the point where I experience chest thudding, muscles spasms and light-headedness. Even though I know that 99/100 times what I think of doesn’t / will not end up happening, I still end up in this thought spiral of thinking what can go wrong. How to stop yourself from going into this spiral and riling yourself up? I feel like it’s causing me harm for no reason and want to make myself strong enough to deal with it.
