Neither was I, however a simple practice has done wonders for releasing the stress, anxiety or "attatchment" to repetitive thought patterns.

I simply sit

cross my legs

cup hands in lap

lightly close eyes to just seeing a blur

breath in through nose out mouth

focus on breath in and out

i count the number 1 over and over as a mantra in my mind

then watch your mind flow to other things and back to 1

don't fight thoughts, observe them as if you are just watching a movie

you will then be able to let thoughts that become repetitive in your mind go and not get stuck on negativity for example

I like to repeat " i am not my thoughts" when i wake up
