Next time you hear this word, just imagine a car.
Thank you for sharing this, I lol'd at the comic and love findng new things/places on the Internet that I wasn't aware of before.
OP: I recently took up meditation to solve anger fits. Medication was attempted for awhile after a series of traumatic events but I ditched them as having feelings, even the inclusion of horrible ones sometimes, is preferable to being shut off from all of them.
Folks new to meditation (including myself recently) can be aided by wearing headphones and listening to calming music. There are works that are specifically modulated and designed to activate the brain waves scientifically proven to be active during the meditation of monks. Try to focus only on your breathing, and how it feels going into and out of your lungs...and "pay attention to attention itself".
If that seems like too much trouble, I find that video games involving the killing of others to not be so helpful. Games that do help me are ones that require focus and passive acceptance of the stimuli, or a minimalist focus on difficulty and goals, such as Rez, Flower, Flow, Fez, etc. It wasn't the intended purpose, but studying and learning new languages seems to have a calming effect on me.
I hope you are able to find peace one day, for me it has been a slow journey of learning and experimentation. The driving force has been the hope that one day I will wake up and feel at peace naturally, and do these things purely for the pleasure they give. If people who have hurt you are a factor in this, try to let it go and create your own path. You don't have to forgive, but realise that grudges only fester within you and that anger will never defeat anger. Best of luck on your journey.
