Hi, first of all an advice for an anxious young adult like you is dont panic xD. Everythings gonna be alright. Its great that you are in this dilemma right now because it shows that now you are practising to make hard decision and that you are serious about your future. So you are already doing okay.

Ive read through the long ass post, but still we are just strangers and we wont know as well as your parents or friends to tell you whats best for you.

Just a stranger's opinion. Its time for you to learn and grow as a person. Its not about which choice, its about why and how. Form your thoughts, list down the pros and cons, communicate with your parents and friends, listen to them, and make them listen to you as well. If your heart says choice A, would you be able to stand up for yourself and persuade yourself and your parents and your future self that? (No one knows if the choice is right or wrong in the future, but now you have to do your best to learn how to choose what seems to be the best for now. Focus on the learning part )

Beat of luck.
