I don't think that this is the answer you wanted but here my extremely unhealthy coping mechanisms: Overeating or eating not enough, laughing when alone without a reason for 10 min or longer, crying every day for an hour before going to sleep or just lying and hearing some sad music, kicking something like an stone or stair, so it will hurt and to handle anger, pinching myself, listing to very loud music, not sleeping at all or sleeping 14 hours straight, lying in bed and looking at the ceiling for an hour, closing my eyes when walking for a while for the adrenaline, stealing some stuff but I don't do that anymore, not looking when crossing the road or crossing when there's a car that could almost hit me, being alone for as long as I can

My somewhat healthy coping mechanism : Drinking water for a routine, writing in a diary
