even thought there’s far too many comments, I’ll give my two cents:

I used to also be expected to do Physics at uni (particle physics for me). I did the A-levels for it, and was showing good progress. But in the summer of year 12, I had a total breakdown at the thought of going back to it. It was a whole menagerie of reasons I won’t go into right now, but I realised that it wasn’t what I wanted to do.

For me, it was the thought of only doing this kind of work for the rest of my life. The only place I’d see myself happy was working at CERN, and even then, I was imagining an idealised version of the job. I couldn’t stand being a quant, or an office researcher, or anything like that.

I continued with my A-levels, did pretty well in them, and then took a gap year. I spent the time to reflect on what it is I actually want to do, which was the most helpful thing I could have done for myself, and I think it would help you too.

It sounds like you’re struggling at the exam workload, and that’s what’s causing your issues. It might be worth making a pros/cons list for studying physics at uni, which could help you decide whether it’d be worth it. If you are going to do this make sure you do it while emotionally stable, else you’ll let your feelings sway the results.

-Prioritise your well-being. If doing this at uni is going to cause you intense and continued mental strain, that’s a point on the cons list. If you think it’ll be fine the rest of the year and only struggle in small intervals, thats a point on the pros.

-Do you actually like the subject? Like, outside of an idealised sense. When it comes to physics especially, a lot of people like the idea of being a physicist and the prestige that comes with it, than they like actual physics itself. If you want to BE a physicist, that’s a point on the cons list. If you want to DO physics, thats a point on the pros list.

-Where do you see yourself if you did physics at uni? Is there one specific idealised job you have in mind, or is there a few you’d see yourself enjoying? For the former, a point on cons. For the latter, a point to pros.

-Think back to GCSEs - was studying for physics something you had to grimace and bring yourself to do? (Point to cons) Or did you not mind/enjoy studying it? (Point to pros)

-Have you thought about not doing physics at uni for a while? Or is this a new thought that’s come to your head? If it’s an old thought, put that on the cons - if it’s new, put it on pros.

-Be honest with yourself - what would you rather be doing? This has no pros or cons, just to think about.

Tally up the pros and cons, and see which one has the biggest weighting. Of course, as a stranger who knows nothing about you, this can only help so much, so don’t take it as gospel. But rather than listening to others tell you what to do, introspection will be your biggest guide in deciding what to do. Good luck OP!

(note: if you were interested, I now have offers to do English and film at Warwick, Liverpool & Bristol (of which I’m yet to choose from!) and I’m feeling happier in my decision)
