Here's my quick attempt at this, but would be good to have a vietnamese native speaker check it.

I'm sorry that I haven't written to you for a long time. I've been ill and I've had to take a break from my studies for nearly a month. Today I am better.

Because I don't have a laptop, I have not been able to write to you. But why have you not written to me?

Looks like you've got some explaining to do, mate ...
