Sometimes, when I'm in a mood where I am extremely upset e.g. something triggered me and I spiral out of control, extreme thinking and unstable sometimes say a friend might text me coincidently (someone who doesn't konw my emotional dysregulation/ dysfunction) and I'll act all normal when I text them. but then right after I text them might text another person who knows my issues about how messed up I am etc. Other times my emotions do mess up things like opportunities or new friendships but sometimes I can mask? It's like I can sorta mask / control my emotions for a second but immediately after doing it go back.
