Dear Elisabetta,
Great to have you on the Forum and welcome!
You are certainly not alone in having suffering from bad temper. I am a fairly mild mannered person, but after 4 sleepless nights and a few bad days, I feel really murderous!! [Then I feel guilty and remorseful as well].
I have found that when I am stressed out, I have to remind myself to be extra careful about snappy remarks or impatience. I play a sort of 'does it REALLY matter game with myself.'
Example, my mother is frightened of open spaces. She trots around the house closing the windows and shutting the curtains. This drives me nuts....! So - I have to get into my game plan. Does it really matter that she does this? I can always open the windows again after she has been into the bedroom, can't I? Positive benefit is that I get extra exercise.
If I get really frustrated, I go into my bedroom and punch pillows. This is a great way of dealing with tension/frustration and I usually end up laughing because it's a pretty funny activity.
Other times, I walk away and go into the garden for a few minutes until I feel calm again.
A few years' ago, I spent 11 months looking after the oldies 24/7 without any care support at all. It was a nightmare and I felt that I was on an emotional treadmill and becoming seriously unstable. I didn't like myself very much at all.
These days, we have carers for my parents several times a week. I am able to talk through my woes with them and also have time to myself. It has made an incredible difference to my health - and to my temper.
Kindest regards,
Jude
