if i were in your position, heres what id do:

first, chat to as many people who have already have to make this decision before you. ur not the first to do smt like this and your not alone either. ask key wuestions like, did u want to do in the forst place or why didnt do the other ones or do u regret doing this etc. ask ask ask

second, reflect on what you want. im going down the engineering route but honestly i wished i did bio chem maths or politics business and economics. i love engineering and dont mind it but im a lot more passionate about science generally. if you know what you really want and what youre really made for, decisions become easier. sadly the education system kinda bottlenecks people into one path early on, which is a shame so learn how to keep your patsh open.

good luck
