For the last couple of months, it have getting worse and worse. When I practice I´m thinking about my breathing all the time, when I put down a chord and before I put down a chord and even during my breaks I count my breathing.

Normally you have to pay just a little attention to your breathing while playing, in order to breath naturally and free.
But I simply can´t stop thinking about it.

I try as hard as I can to relax and forget everything, but it keeps confusing me, mentally.
Has sombody else here had this experience, and what can I do about it?
