I get major separation anxiety with my girlfriend. It's not even like we don't see each other that much. Our last date was a month ago (her parents are strict and have filled up her schedule for her so she doesn't get much free time anymore), but I have first block with her every day, second block with her every other day, and lunch every day with her. We just got back from a 4 day band trip to Disney World and we were together from breakfast at 8 until room check at midnight every day. But when I got to my room, I was always hit with a wave of sadness. I'd stay up late talking with my friends about sports and girls and food to try and sidetrack my mind, but the truth is, every second I'm away from her, she's invading my mind. I have trouble sleeping at night because memories of me and her cuddling in my bed flood my mind. I can't get the thought of how empty and cold my bed is without her out of my mind. I've had the same nightmare for the past two nights. She'd be standing on the far side of the hallway. I could hear her beckoning me to come towards her. I'd try to walk, but my feet wouldn't move. We would shout to each other hysterically. No matter how much I tried, I couldn't get to her.

Tomorrow night, she leaves on a flight to the other end of the country for spring break. 2458 miles away. She gets back the day before our seven month, and we were able to convince her parents to let her come over that day, which I'm ecstatic about. But I'm fearful for my state of mind while she's gone. I'm desperate for a way to rid myself of the anxiety.
<bot>: My girlfriend is going to be 2458 miles away for a week and I get major separation anxiety. I need a way to get rid of it.
