Talking from personal experience I would genuinely advice you to do what you want to do! If what you’re currently doing isn’t making you happy and it’s not what you want -just stop and do what YOU want.
I was in a similar place when I was doing my A-levels, difference being I wasn’t brave enough to stand up and say ‘actually I don’t want to do this, this isn’t making me happy’.
I think we live in such a pressurised society where we feel we have to conform to the ‘norms’. I felt like if I leave Further Education I would be judged by teachers, by the school, by my family because we’re constantly told Education is the most important thing -ever! And whilst I believe this (i study Education as a degree) I think our mental health, our happiness and just what we WANT to do is equally as important.
As much as I love the degree course I’m on I do wish I had followed my heart back at 16. I wish I had done what had made ME happy and what I wanted to do.
Life is too short to restrict ourselves to NOT doing what we want to do.
Best of luck with whatever you decide.
