I used to drive myself crazy over thinking even the simplest of things. Making decisions was ( and still is to some degree ) a nightmare. But then i have purely obsessional ocd alongside bp so that hasnt helped. I have been doing a DBT skills workbook that has really helped and my new mantra when i start to get caught up in my thoughts is " I can only deal with the present, with this exact moment in time " ... so far it's working !
