<human>: Can you succinctly summarize the text in 1-3 sentences?

So, lately, it's been ridiculous. She's gone on vacation up to San Antonio multiple times and I live in Austin, Texas. She's up there so often because of family issues and whatnot.
So, typically, I can text her 24/7, no issues. Just talking. But now that she's up there, it's been crazy. This past month, I've literally never been able to sleep in.. At all. She makes me stay up to talk to her, until about 1-2am. Then I wake up at 6:30am to go workout and get ready for work. I workout for a solid 2 hours and head to work, then I get off at 5. I text her throughout my work day, and even when I get home. I can't even take a nap without her telling me she's upset that I'm not talking to her. Today, I took a much needed day off. I started playing video games, so I'd reply to her like every 5-15 minutes. That was too long of a time for her to wait, so she told me to step up my game and text her faster. So, I did. 
Here's another instance, yesterday, while working on a project for work, that was due at midnight. It's about 7pm, I'm working diligently. My phones on the couch beside me and she tells me that I should drop everything and talk to her! I did that! Then within 5 texts later, she tells me that she needs to go and that she's sorry she forgot. I get it, she forgot. It happens. But literally, it made me furious. I could have been working on that project.

Pretty much, how do I tell her to give me some space without sounding too rude? This isn't a newby relationship, we've been together almost 3 years now. So I guess it can be considered new to some.
<bot>: My girlfriend is super clingy, won't let me nap, sleep, go to the gym, do anything that requires my time, besides text her.
