@Dosed,
Dosed, stressed and probably also because it takes a bit of time getting used to someone being a distance from you and only a telephone for communication, especially when you are in a happy place with that person:)
If I could make a suggestion to you other than what the others have made that you have followed up on, and that's great, is to forget your past in as much as, you have found what you want in a man, and he loves you... And, maybe in addition, start writing your own blogs, or journey , or find something of interest a hobby outside of homework... Sometimes if we are alone too long, we think too much:)
Something fun to do, will give you something also to talk about to your boyfriend as well as take your mind off of him being so far away from you at the moment.
Best wishes
