Dont beat yourself up because you didnt live up to promises you didnt make or didnt want to, idk what happened with system, like you said yourself the Nutella is over, the person who calls you poisoned is just trying to get attention, the one telling you to thy is a showerless, basement dwelling Twitter warrior who you shouldnt pay mind to, and your friend leaving sucks but that doesnt change the rest. Whether or not you leave I dont care, but im just saying, if the general consensus is youre chill the only thing persuading you to stay or not is if it make YOU comfortable. I also don't have a good grasp of what exactly happened with a lot of those, but the point still stands.
