For a little while I have been sitting down to meditate and finding the whole thing quite relaxing. I'd notice a few breaths, then a thought would pop up and I would notice it and let it pass.
However I sat down this morning and realised that now can't even do a simple inhale without having it smothered by thoughts. I believe, in hindsight, that I have been thinking all the time, without me noticing. Usually it's like a meta thought -thinking about how I am thinking, or thinking about noticing a thought "Hey comes a thought, okay let's notice it and not get attached."
Feeling pretty discouraged right now. I feel like I am in a rut.
I have the impression the answer will be to "keep practicing!" Given that meditation is probably the only thing you can't think your way out of.
