<human>: Can you summarize the given text in a few sentences?

A brief background: Been with someone for 2 years now, Its been an amazing journey and we both love eachother like crazy. But she lives 20miles away so we don't get to meet pretty often. I'm in university and she's in High school.

 Now the real issue: She's someone who knows she has to study and takes no shiz in front of it, gets obsessed when her exams approach and hardly ever has time for me, will reply like once every hour or two to my texts and talk on text for like 20-30minutes before she sleeps, doesn't even skype or call during exams 'cz it wastes her times.'The issue with me is that Im used to her being there all the time which is normally the case and I have a hard time dealing with her absence that I spend my day merely in wait of her reply.

Its like I obsess over her a lot and it gets unhealthy at times and I need to build my own life. I need to study really bad too but all I do all day is wait for that one text from her and the cycle repeats for the next hour or till she texts. Even other than during exams, she goes where she wants to and everything and has a life other than us too but all I ever do is wait for her when she's not there and talk when she comes; because if she's there and I go away to be busy I feel guilty at wasting time we can spend talking.
How do I stop obsessing and build a life of my own too? The only things I do regularly are hit the gym and hangout with my uni friends for about an hour after class, other than that Im only waiting and replying to her all day even during class and its high time I do something abt it and start studying..
<bot>: So like, How do I STOP Obsessing and basing my entire day around her and instead make her just a part of it like I am for her, study when I need to and do everything and manage our relationship too..
