I am sorry you are dealing with this particular issue, BuckeyeCurt! I can see how it would be very frustrating! Many of our members deal with bouts of sensory overload.
Also, the sensory overload issue is a pretty common one within the MS community. Really, if you can start to find your triggers and either avoid them altogether or design some coping mechanisms ahead of time, it may help you combat the fight/flight response that overload is triggering. Whether it's removing yourself from a situation, closing your eyes, wearing sunglasses, or (my personal favorite) wearing headphones or earbuds but not actually listening to anything through them; whatever it takes to help you manage sensory overload is fair game.
So, with fight or flight responses, your body is probably dumping a nice bunch of adrenaline into your system. So, that adrenaline energy has to go somewhere. Hence, the angry outbursts. If you can't avoid the sensory overload, trying to get some of that energy out may help. If you are able to do some mild exercise or even some deep breathing exercises, those may help release some of that adrenaline from your system and help you relax.
And while these tips may not help in "the heat of the moment", I thought some of the suggestions in this article might spur some of your own ideas for combatting your body's stress response -- https://multiplesclerosis.net/living-with-ms/7-ways-to-fight-stress-and-anxiety.
I hope this information helps! Thanks for reaching out and good luck!
