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

Okay, so, I need some advice. I'm headed to Beirut in the next week and a half and I'm freaking the fuck out. Our relationship has pretty much been on the downlow for the better part of the time.. We've been dating 3 years now. She's a Muslim, granted a not very conservative one (she's still a virgin), but other than that, she's not conservative at all. She's become an American for ME. I can't even express how awesome that is. She's become a HUGE success compared to me. I'm just a Marine who has a few more months in before EASing. She's recently got accepted to one of the nation's best medical schools, and she's a huge volunteer and all that. The thing is, I don't know how to even remotely do the whole meeting the parents thing, and I'm not too sure if I can even remotely live up to their standards. I asked her about it, and she said not to worry too much, but I can't help it. I feel inferior to her and her accomplishments.
<bot>: I feel inferior to my girlfriend and especially since I'm meeting her parents, I want to leave a good impression, but I don't think I can.
