Boyfriend going to college

I am a senior in high school, my boyfriend just went to college in Texas. (we live in Chicago) we're taking a break while here's there, with the hopes that when he comes home on break we can still resume a relationship. However him leaving is much harder than I thought. I am so upset and it feels like everything reminds me of him and how he's not here. This is so hard for me. Does anyone have any advice or support? Thanks. ❤️
