Answer:
if I were you I would spend some time just for myself. Just focus on who you are and what you want to be or just spend some you time alone, no distractions, do what makes you happy, like when I get this way I listen to my favorite music artist. If you spend time focusing on your self you will slowly decompress. Another way to get rid of stress is to take breaks in between each homework assignment or class (if your a virtual learner). Go to your "happy place" whether its a place outside or your room. Take things one step at a time. If that doesn't work try talk to someone you trust, maybe its a parent you have a good relationship with, yell about your problems, cry, and scream (warn them about the yelling before hand) or buy a pillow for destruction, like you scream into it or hit it. I really hope this helps (sorry about the bf thing, be happy and find the light at the end of that dark road)
