I know how you feel. I think it's nightsky who used to post how to get through the bad times, 1 minute at a time. Just take it minute by minute. Crying is good. I've done a lot of it this week. Maybe now you can do something relaxing or distracting.
I hope this isn't triggering, but do you live with your parents? Do they know how bad you feel? I understand if you don't get along, but just wondering where they are in all of this. Please forgive me if my questions make you feel worse. I'm trying to help you get through this and asking out of caring.
