@26aqua Thanks for sharing your story, I  to have experienced very similar feeling of Agitation, irritation and aggression in my life for over 30 years and for me it is the most intense, tiring and shameful thing for me. I lost a marriage, friendships, jobs and even put in jail over night for the intense rage I was in and damage I caused.. That is why with my profile picture, is a picture of the hulk.o I feel for your situation and knpw it quite well 26aqua. But about 9 months ago i getting therapy with a psychologist called CBT and has been life changing for me, if gave me the skills to reconise when a bout of rage was coming on and tools to defuse the intense feeling  I was having, also mindfulness therapy which kept me a lot calmer so the bouts came a lot less frequent. So if you are willing to give it a go, organise an appointment with a psychologist and speck to him about CBT and mindfulness,  they therapies do take a bit work on your behalf and time as well, but me patient because it does work and you have nothing to lose but the rage you are feeling, best of luck 26aqua, your not alone and there is help for out there.

Warm Regards
