I would say a large part of this depends on you being a Faraax or a Xalimo.
Without asking and going of from your words, it seems to me that you like working with animate things (animals, people, in groups etc) rather than inanimate things (material, structures, abstraction, programming etc).
I would say this dichotomy of object oriented and people oriented split is as real as the left brained and right brained split, and sex is the single biggest predictor of it. Its for this reason why you see so many nurses, teachers and doctors being female. This is a dirty thing to say, but its been my observation.
A large part of engineering involves practical engineering and a healthy amount of paper work, such as finalising CAD specs into PDFs, micro managing minute abstractions, often on your own, only occasionally meeting up with higher ups for progress reports.
Being an electrical engineer in highly developed nations like the UK is uh... something. My brother is one, he works 2 days from home and goes in 3 days, he stresses there is hardly any difference.
A large part of his work is just satisfying healthy and safety codes and baby sitting Indians. For example, his current project at Heathrow, the company out sourced large parts of the electrical designs to a second company in India, so he gets sloppy work every week that he has to sanitise, before submitting it, he has given up telling them how to do it properly.
This appeals to a lot of people whom may not necessarily be introverts, but who certainly want to be left alone to their devices.
I am not discouraging you from going down the engineering route but only do it if a large part of it appeals to you, in and of it self, not primarily for the money. That you see yourself spending long nights alone on your own, dont think that will only be so during your studies, it wont. It only gets worse on the job.
I am currently trying to solve this very problem, for example I am trying to
set up a social group for software/hardware engineers, and so far I have had 1 person wanting to join, that is it.
There is a healthy balance to be had; don't choose a career solely on "muh pashuun" nor just for the $$. Nobody likes the guy who spent £70.000 on a useless history degree or the office drone who is dead on the inside.
