I know what you are saying I can't even count how many telephones that fell victim to my rage. I can tell you that one phone handset went through the wall after making a boom as it crossed the sound barrier!!! I tend to keep a cap on the worst part of my rage contained when I am face to face arguing with someone but if someone I'm arguing with on the phone hangs up on me then it ends with a trip to wally world to buy a new phone.
Now for an important question do you feel better after a rapid outbreak of rage or does the rage stay with you for a while after you do something like throwing your coffee across the parking lot.
For me I feel like my adrenaline goes through the roof in a instant but once released I feel much better. Sometimes some controlled breathing will help me keep a cap on things till I can get to a place where I can safely let out that negative energy. This takes more than just taking a deep breath. You have to visualize that you are inhaling positive energy and exhaling negative energy.
Next is to find a safe place and way to release that rage. Punching bags work well(very well if you have a picture of who ticked you off in the first place and some tape) But any way to give you a safe physical outlet to unload that rage.
Now you might try to do some anger maintenance. Find something to do a few times a week to let out the anger that comes with day to day life before it builds up. If you are already full of pent up rage then something happens that adds a lot of rage quickly then you end up over the breaking point. That means you are much more likely to unload all at once right on the spot.
I forget if you have a T or not but if you do you should talk to them. If not and the steps above don't help then you might see if there are any groups in your area that teach anger management.
Coop in some aspects of rage we do have a choice. we can try to avoid things that might set us off. We can also work on keeping ourselves from letting things build up to the breaking point. Case in point you mention a pressure cooker. We use pressure cookers all the time and rarely have a problem with them. But if we fail to maintain them and the release vent gets clogged or a worn out gasket fails then it becomes dangerous.
But that is not to say that all aspects of anger and rage is something we have a choice over. But we do have a choice in how we react to it and how long we carry it. With all that said I won't promise that all the phones in my house are safe but my razr cell has lasted a year now.
Give some of this a try to take care my friend.
