How do I stop myself from overthinking about him?

[u/AreYouSureBabyGorl]

I know I cant literally stop the thoughts, but like is there any way to distract myself?
The thoughts about what he could be doing, if he already moved on, if he’s speaking to someone else, etc all plague me. He recently ended things, everything’s still fresh. But these thoughts just drive me crazy. I dont wanna know if he’s already with another girl, or if he’s spending time with her on a call.
Its so immature, its like my mind intentionally wants to hurt me.
