Welcome christinaaaa!
I know, ran into you elsewhere, and so we've already technically made our introductions. But, i still like official hellos. Don't worry, you have a good chance of passing since you have the right facial structure. Plus, a lot of that actually depends on the smaller things like how you carry yourself and your speech patterns ("may i have a small shake" instead of "gimme a small shake" for example.) Things you can learn. Just don't rush things, you'll be glad you didn't later, And don't forget that everyone's experience varries a bit.
I hope you enjoy your time here, i doubt you'll find a friendlier or more understanding crowd. And, please don't be afraid to ask for help.
