I can relate to this a lot. A technique you might wish to entertain is the "beginners mindset". The idea is to approach a situation or problem as if you were tackling it for the first time, or had absolutely no prior context to work from.

The thinking being that some (all?) of the side assumptions your brain is fixating upon developing responses to, could in fact be erroneous. By experimenting with adopting a "noob" mindset, you create the opportunity for new experiences to emerge which may well be more successful.
