Help Please

I do not really know how to tell my mom that i have to repeat the year.
Overall I've always been a pretty good student, but this year wasnt really my year.
I did pretty well on the english final exam (i got an 1=A+), in math it was an (grade 4=D)ok and i dont know what i have in german. I have good grades on evrything except math, chemistry, and physiks (all of them grade 4=D). And the grades of the other classes can't balance my bad grades. I would really like to repeat the year because i couldn't concentrate due health problems and so on.
Aside from repeating the year I have the possibility to do an apprenticeshipp in a occupation that i would like to work in the future. After this training i would get the opportunity to continue with my school education. Problem here is I'm lost and don't know what i would like to work in the future to choose now a training.
Any Ideas could help.
Thank you a lot <3
