Someone Tell Me I'm Overreacting

Alexa

My boyfriend of a year and I have both just moved to college; we've known for 6 months that we'd be going into a long distance relationship and the adjustment has been difficult. The most difficult part has been communication especially with the new time difference with him being an hour behind. I always text him before and after class so he knows where I am if I don't respond, I tell him when I'm going out, and I make it a very big deal to FaceTime with him. On his end, however, its mostly silence. After I noticed this I stopped texting him for the most part, since I don't want to come across as clingy or annoy him. I've only heard from him 4 times today, the last being 5 hours ago. Due to the change in our relationship and the change of moving to college paired with a pre-existing anxiety disorder, I can't calm myself down. I'm worrying myself sick and I don't know what to do. Please, someone just tell me it's going to be okay?
