Lost. Dazed. & Confused

Its been a week since my and my boyfriend ended things. I have cried everyday since then. Every morning I wake up thinking okay that was just a bad nightmare, but then reality sets in then the tears come. Some days I cry cause I miss him. Some days cause I miss him mom. Some day cause I miss his family. Some days because I miss the text messages, the hugs, the kisses, his laughter. I cry because I regret being upset, and not showing up to school the following Monday after our huge fight. He is confused I know he is. He keeps saying that we will never be past friends again, and that its for the best. I have been trying to cope with this. So far I have been doing a bad job. I cry every morning. I cry sometimes I fall asleep. I see him in school, and I try to hide my feelings but it doesnt work all the time. I simply don't know what to do anymore. I can use some help. I want to write him a letter, but Idk if that is the right thing. :/
