TS (thread starter) already said 'teenager'. So around sec
school to poly lah.
I dont think TS at his/her tender age can do much to resolve the
parents' problems.
TS just concentrates on your studies and dont let your
parents' problems overburden you.
If can, find a close, trusting relative, eg uncle or aunty, whom
you can confide or unburden your problems with.
This will help you see your parents' problem from adult's
perspective and hopefully he/she can also intercedes
between you and your parents.
If the above not possible, your problem is minor, seek help from
your school counsellor. Else major, seek help from a
psychologist.
