Out of the country

My boyfriend is out of the country in the other side of the world right now for two weeks. I knew I would miss him but I didn't realize just how much until his plane took off. We don't live together and we FaceTime and snapchat through the day. Every night we used to talk on the phone and every morning he would give me a hug and a kiss and I miss the little things like that...I know it's not for a long time like some couples out there have to deal with but its like my heart is on the other side of the world. I can't eat, all I want to do is sleep, and I'm sad all day. I had pretty serious depression a few years back and this feels like a slightly toned down version of that. I feel crazy and clingy but whenever we talk he tells me that he feels exactly the same way. How do I get through these next two weeks? I know that this sounds really silly, I just miss him so much.
