Ouch I remember mine. A sore memory.

***This may trigger by the way, sorry.

I was about 14 and I was having a house party and having a good time as usual. My excitable energy turned nasty and I blacked out. Its not unusual for my happy energy to turn bad, I have to be careful not to lose control of it. The next thing I remember I was sawing in to my nose on my doorstep with a blunt kitchen knife.

I stil have the scars today (12 years later omg im getting old) and have no idea why I was doing it.

I hope you nip your angry mania in the bud, I agree with the above post, exercise might help? just find a safe way to try and release it
