Breathing while playing

[mikkeljs]

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?
