Dear Tom,.
thank you for your letter!
I'm sorry for your drain. If i were you, i would talk to my parents about this situation. Talking about things can solve many troubles.
My parents understand me perfectly, they understand that my opinion may have differ from theirs, they trust me and almost don't put pressure on me.
Any parents can be "ideal". A good parent should have patience for his child, support his ideas, and not ruin the passion to study, sport and hobbie.
With love/all best/best wishes,
<your name>.
