Dear Tom,
I'm sorry to hear that you have a big problem. As for your trouble, here are my suggestions.
First, you should communicate with your parents and tell them your feelings.
I believe that they can understand you. Second, in order to relax yourself,
you can take some exercises and listen to some relaxing music. Last,
why not make a more reasonable timetable to study?
And you should remember that God helps those who helps themselves.
Therefore, you need work harder for your dream.
Best wishes to you!
Yours,
Jack
