I have a saying: 'if you're afraid of losing something, then you've already lost it'. Oneitis and neediness kill attraction, and you're being superoneitis and superneedy right now. Basically, if you're going to skip work (worth 2k, WTF) just to see her you're going to kill the relationship with your bare hands.
She initially got attracted to you because you pretended she was a fat girl you didn't care about - now you're thinking of doing extreme things because you can't stop thinking about her. You're doing the opposite now and the result will be the opposite, too.
Stop thinking about her, just do your work, and when you're back home hang out with her. Keep texting to a minimum unless you're good at it and have read decent material on it so you can do what whitedragon suggested, because it can be a one-way ticket to the friend zone.
