wow dude thats rough. id lose it too with them there. i do similar things when extremely overstimulated anxious or stressed.
screw them. just do what youre going to do with school and driving, etc and let them be miserable and negative all the time.
just completely ignore them. when they dump all on you like jerks dont even respond or show any emotion, suck it in as hard as it is. that will surely annoy them that theyre not getting to you. dont let them see how much they upset you bc it seems like they feed on that and then push further when they get the reaction they want from you. thats awful. keep your head up and just focus on what you want to do.
