Anxiety and Long Distance?

Any tips on how to work through this?

My boyfriend and I have been dating for a little over 2 months now and overall I would say I'm pretty happy. He's a great guy, but he lives in another state and because of his job, it's hard to keep in contact. The long distance hasn't been an issue, but I'm finding that the lack of contact is slowly starting to trigger my generalized anxiety more often. (Not because I don't trust him, more because I'll get irrationally worried he's not invested anymore). It's a new relationship, so I don't want to rock the boat by throwing a whole bunch of emotions down. I know this is something that I should just talk to him about, but the anxiety around even having the conversation at all makes things difficult.
