Dear Brother,
I know you were having a hard time in your studies, I am also sorry if I cannot help you with it, but please you should think about what are you gonna do about your decision right now, after all you might regret it later. You just have to remember, do not stress yourself, keep calm, if you're getting troubled, feel free to ask me for help. I would be willingly help you out in your studies.

You can try having some relaxation before and after your studies, just remeber, Do not Stress your self. Write me again a letter if you're feeling much better. Take care Brother.
