Not sure what to write... can't explain these tears.

I don't know if I'm just overtired and my emotions are getting the best of me, or if it's something else. I feel like I'm slipping into a depression again, but I know I get like this when I'm severely sleep deprived.. Every little thing upsets me. My boyfriend canceled plans again today be arise he had a severe migraine, he's canceled plans before because he isn't feeling well and for some reason it gets to me... I just really miss him. We dated years ago, he was the love of my life and the first person I ever had sex with back when I was 16.. The love never went away, love like that doesn't just go away. I can see us having a family together, we've talked about it already, he's the one to bring it up too! We're happy, just busy... I'm not happy that I never see him though.. Our one main day to spend together is Wednesdays, I don't have class and he usually gets them off, so it just sucks when he cancels and I have to wait another week to see him. It's hard... First world problems.
