Tink yes, i do the same. I tend to obsess about things going on in my life, which makes it harder to focus on other things.
While my son's health is not what it should be, and him having to keep going back for tests is something i obsess about.
Last year when my husband was ill, i couldnt focus on much else.
When one of my fur kids are sick i stay up all night to make sure they are ok.
The way i am trying to change my habit is to visualise my life the way i want it to be, so instead of focussing on the "troubled" areas, i try to look beyond it, and live the way i would without all the "drama"
I have found that, if i focus on the not so good parts, i feel that im feeding those areas.
Dont know if that makes sense
