Not enjoying my apprenticeship.

So I started an electrician apprenticeship in October (Im 20, UK) I was previously doing Steel Erecting but broke my collarbone which lead to me not being able to continue doing it, I would maybe want to go back to it as its run in my family, but id most likely have to do an apprenticeship for that aswell I think and it is very bad in the winter. Last year I worked at a golf club restaurant/bar and it was so good was well paid for what it was, there was no stress ever I had a couple days off every week life was really easy and enjoyable. With this apprentice I am doing right now Im just not sure its for me I go to college every 4 weeks for 4 weeks which isnt very fun there is a lot of Physics & maths involved which I can most definitely say is not my strong point i never did it in school a lot so Im clueless at this really, there is stuff to be handed in every few days which is so stressful and its only going to get harder. im a good practical worker, but every day I just dread going to work and not sure I want this for the next 4+ years, It is an amazingly well paid job if i get qualified at the end of the 4 years but I dont know if I can last that, I want to do it to make my family and gf proud but I dont know if its worth it, Im not enjoying life really and surely its more important to do something that makes me happy and drives me to work, But i have no idea what I would do? im a pretty sport person and love football but doesnt really help. Last year just working in the golf club was so nice and stressfree but I cant just do that forever.. I just thought id post this to see what people think, its a big post but there we go,

Thank you.
