Here are some suggestions for you. Good luck with your letter. :)
It’s good to hear that you are doing well! Last time
whenwe met I figured that you arewere tired. I’m sure that not being able to go home after each work day itselfwould be very tiring. If you let me know your schedule in advance, I would be able to work around your scheduleit.
Also I'd probably change "I figured" to "it seemed that."
I might also change "I would be able to work around it" to "I'd be happy to work around it." (either works but personally I'd opt for the latter).
