Can't Breathe

I just started being able to breathe again. I just walked home from ending a friendship...and i was crying the whole way. I am starting to calm down. I didn't think I was going to cry too hard, but then I saw her face before I left, she was hurt, and she had tears in her eyes. She was the one who was trying to make it this way in the first place, to make things better for me. Now I did half of the ending.
I guess she isn't supposed to be my concern anymore, but I can't help it. Ugh...i am having trouble breathing again. I don't feel like eating lunch anymore...
