How to stop caring so much?

Okay so I have been with my boyfriend for 2 years, he took my virginity and I'm very much in love with him. But I'm starting to get controlling, never wanting to get off the phone with him, and to the point where I'm annoying. I am home schooled, I have no friends I talk to or hang out with and I don't play sports I just sit at home. My boyfriend is in the army and stationed in Colorado and I live in Florida. What can I do where I don't put so much pressure on the relationship with caring WAY to much. Like getting mad about stupid stuff or never wanting to get off the phone? Please help me, this is tearing me apart because I'm pushing him a way!
