Fellow engineer here, but from the opposite gender, from a speciality that has very little female representation, even when compared to other STEM fields.
People are assholes for all sort of reasons, you have a particular set of complicated arrangements, but each have their own. I don't want to understimate your plight nor I'm gonna say that you have it better, because honestly you don't, but everyone you go to college with is, to a degree, going to something similar to what you are going through, only with a slightly different set of insecurities.
So what happens is that you chrash straigh into many of these people's insecurities, which are fairly common among STEM students, you are as clever as them, if not more and on top of that you are charming and attractive. There are also, ofcourse, those that go with the penis first, but I'm fairly sure that you have met those before you got into college. Back on topic, these people have been often the most clever people in the class or on their groups and thats what made them easily shine, and here you come, and suddenly not only you match up to them with your brains, but totally roll over them with presence, so they got stupidly and inmaturely defensive, because, how could you look so good and be as intelligent as them AT THE SAME TIME!!!
I, of course, as a rather average male didn't face the scorn you do, but I spent 5 years in my degree and I didn't get a reliable partner for my lab classes until my last year (2 semesters), and before that I got lucky twice with a partner that didn't leave me alone with all the work but still didn't do that much, 3 of my 5 years I had to eat my group classes (usually groups of 2) all by myself. My study group was formed 3 years in and consisted of the only 2 people I could call "friends". Don't get me wrong I had plenty of acquitances, I've always been a very diplomatic dude, but they where there when they needed something. My first year on the degree (I transfered from Physics) I was made fun of because I had the foresight to rent a locker, in fact my nickname for ALL my years was something that would translate like "Lockerman" (Lockey for short), which didn't stop my classmates to every so often come and ask me to let them store something in my locker.
People are stupid at that age and are figuring shit out, others are more malicious and trying to come over you whatever the cost, other they only think on themselves and only remember you when they need something, this is law of life and its somewhat hard to accept, but society in general is only interested in what you have to offer and there is a bunch of people that its trying to set you out of track to have it easier themselves. I know now are hard times and its easy to give up but please don't. Not so far in the future youll have a lot to offer with your degree and there will be plenty of people that will appreciate you for what you do, and probably also some others that will be jealous for you, but there is always going to be haters. Learning to work with people that you don't like but do their shit right is a very useful skill to learn, also very hard and difficult.
Push through, every hardship you find now its valuable experience for the future when things get at stake, don't give up, it's not like life gets easier, but you certainly grow more tough and resilient to a point in which you will draw attention not because your looks, but because of how easy you make all look to be.
