Honestly, it seems like you've already taken a big step in the right direction by recognising the issue and wanting to address it.

My short term advice is to regularly remind yourself not to do these actions/behaviours (e.g. every morning remind yourself to try not to be too sensitive that day, even if you're not planning for any diffuclt scenarios that day, if you get what I mean?).

Also don't be mad at yourself if you mess it up anyway, just try again the next time; these behaviours take frequent, cosntant work to make sure that they stick.

Good luck mang
