Why can't I come out of it?
Anyone have some tips?

I overthink about the same thing until it feels like my head is tingling/burning.

In the mornings I wake up having a panicky/anxiety feeling then I overthink about the same thing to try and "solve" it or reassure myself.
At some point in the day I manage to somewhat reassure myself and tell myself to not think about it.

Then later in the day I'll manage to link something/anything back to the thing I was overthinking about until I repeat the steps above. I'm exhausted. It's impacting people around me, my husband and family. I don't get much done on days it's really bad.

This happened to me around 10 years ago and lasted years and nearly broke me. I managed to eventually snap out of it and be somewhat at peace and dare I say it, even happy. Now it's back with a vengeance and I don't know what to do.
