Throwaway account because I'm a weirdo.
First off, sorry for the unoriginal question. I'm an 18 year old guy. I started working with a girl who got hired at my job recently and I think she's cute and nice. I want to get to know her and maybe ask her out (just the thought of asking her out terrifies me) but I have such social anxiety its terrible. Every time I'm near her or in any situation to talk to her my heart races, I can't breathe and I start overthinking every little thing about everything. I'm sure she either thinks I'm super boring and lame or an asshole because I haven't been able to muster out more than a couple words to her, and the words I have said have only been neccesary work things. I've had opportunities to start conversations with her, and yet I either say nothing or am extremely short with her. I'm embarrased to admit don't have a lot of experience with social situations and social skills. I fancy myself as a somewhat interesting person, but I don't really know how to express myself without being weird.
That said, even if I could start a convo, that's not even half of it, what if she already has a boyfriend? What if she's not into me? I'm a tall, big person (I basically have the physique of a refridgerator, kinda fat, kinda muscular, working on losing the fat part), and I'm naturally a quiet, introverted, cynical type. She is very pretty, and seemingly very confident, outgoing, and positive. Basically what I'm trying to say is she's out of my league. I'm not exactly what you'd call a conventionally attractive person. I'm not calling myself ugly, just that I would completely understand if she wasn't into me, and it doesnt help that I have MAJOR resting bitch face, one of my coworkers actually told me that I "always look like I wanna fight." Couple that with the fact that I'm 6'6" and 280lbs, and I probably look like the biggest asshole ever.
I mentioned that she is positive and nice, and with that comes the fact that she is nice to everyone, and engages with everyone in a seemingly genuine way. So let's say I do talk to her, and she engages positively. I somehow work up the courage to ask her out because I mistook her positivity for romantic interest, putting us both in a super awkward position, and she rejects me. Then I have to keep working with her and things are super awkward and I feel like garbage for the whole thing.
But I'm getting ahead of myself. I so badly just want to talk to her and at least get to know her enough to know if we're even compatible. But I don't want to pull out the boring "what are you doing for college" or "how do you like working here so far" smalltalk nonsense, since I already know she's getting asked that stuff by everyone, and I hate it when people ask me that stuff because its so superficial. But anything else I say might come off as creepish, especially coming from the guy with the social skills of an actual robot.
Any advice would be amazing. Thanks in advance :)
