obsessive thoughts

I’ve had periods of spending more time inside my head, rather than dealing with the outside world. Once for a rather scary length of time - around 18 months. I don’t know if this what you mean.

The following article may give you some pointers in how to break the cycle.

Hi, NAS64188
I'm sorry you feel that way. I advise you to talk with your close people or seek help from a psychologist. The second option will help more likely. Sometimes even one consultation is enough. Take care!
