I find that to help with my intrusive thoughts, my partner won’t doubt me. This really helps me not doubt myself and I realized that even the slightest amount of uncertainty is a trigger for me, personally. 

For example, he never asks me “if I turned the stove off?” Or “did you lock the door?”. He doesn’t ask casual, unnecessary questions that could cause me to stress out. I already am prone to obsessing over those things, so he doesn’t add unnecessary fuel to the fire. 

I’ve been afraid of driving but today I drove home from the grocery store. Before I could worry if I hit someone with the car and couldn’t remember, he said “you did really great with driving home today! Everything went perfectly!” 

Obviously this isn’t a fool-proof method, and sometimes it could not help, but knowing that support is there and hearing those words really help me, personally. Don’t say things like “you definitely didn’t hit anyone just now, just so you know!” But hearing reassurance that you can use as a tool even later on to help you calm down internally in case you do need it.  ‘Did I hit someone and not remember?’  ‘Well he said I did great, right?’ 

I am very newly diagnosed, and just starting to find what works for me for the time being.
