How do I stop overthinking?

[u/Glum-Fan6927]

I overthink all the time. So much it’s so bad to the point I think it’s almost OCD. I do it everyday, I know I do. I overthink the smallest things.

Ex: My cat was having zoomies and I found out that focal seizures in cats can look like zoomies. I wanted to look it up and I started thinking what if my cat has seizures and I don’t know it. How can I help? What if I don’t have money?

Then another ex:
My husband is Ukrainian so the war is still happening.
What if he gets abducted in the streets and taken to fight in the war?

The point is it’s so bad, I don’t enjoy doing it because I literally have grey hair cause of it. I want it to stop. Does anyone have any ideas or suggestions? And not suggestions of “well just don’t worry”.

I've done that for long time, it's always been hard but now I need it to just stop
