Since it is such a trigger, you know that there is some healing you are needing that is either something you haven't dealt with or not dealt with as completely as you possibly need to.

I have found that when something triggers me, it's my subconscious telling me that I really do need to deal with the issue in a much deeper level. Many times we think we have dealt with something but have only touched the surface.

Maybe after you have been able to work through your trigger, you will be able to help others who struggle with the same triggers as you are dealing with at this time. Know that might sound a bit much at this point, but something that in the long run might help you heal even more.
