Feeling down

I'm currently 600 miles away from my boyfriend (I travel out of state because my dad works out of state) and whenever I'm 600 miles away I feel like the worst girlfriend ever. I'm never physically there for him and it makes me feel awful. Last summer he tried to take me to the fair and I couldn't go cause I was out of state, his swim team just started up and I know I wont be there to go to one of his meets so I can only text him and say good luck but I wanna be there for him and I never am physically and I just wanna cry
