Mine are intellectualization (thinking very logically, in “black and white” like my friends say), sublimation (weight lifting is cathartic for me, it releases my tensions and anxiety) and altruism (talking to people who need help, mostly when I post replies to people asking for help on this site, going to parties and driving people and taking care of the drunks, show them where to puke and give them water and put them on couches to pass out).

They were the only people who I spent enough time with to trust and also provided me with self medication and support.
