The short fuse, as crystal calls it, is common to PCS. I find that I need to avoid the triggers rather than try to deal with the triggers once they start to cause trouble.

Recognizing the triggers is the first step. Then, a request for someone to turn the TV or music down while you step away BEFORE you start to feel the pressure building is the best solution. It is no different than a blind person requesting the family to stop moving the furniture.

It is not unreasonable to make these requests. Family and true friends will understand the need to get on board with this issue. They need to understand it is not a personality choice. It is your brain jumping into fight or flight mode due to the over-stimulation.

It may take a few serious sit down conversations to get cooperation but the others will benefit from the support they give you.

Hope you find help. I know how much trouble the outbursts can be.

My best to you.
