I have bad anger problems too. I have no glass or crockery in my unit due to when I have a meltdown I have plastic cups, crockery and forks and knives. I get aggressive and violent too, if I dont understand the situation or if I get suddenly woken up without knowing whats going on I have a meltdown and if I get roped into my friends fights and dramas and they involve me in it I get aggressive and violent start crying and screaming at them it takes three of my friends and one of my friends Mum to hold me down and settle me down. I dont like loud noises especially fire alarms, smoke alarms, car alarms, car horns, loud parties with high treble music my neighbour upstairs had a party and I had a meltdown and I went upstairs and nearly kick their door down I put a hole in their door. I only buy cheap mp3 players and I have my xbox 360 kinect, ps2, two TVs, set top box, sound system and computer up high and far away from me if I have a meltdown.
