Hello Jet, I think that's a good idea. I was going to suggest keeping if brief. Maybe you could say a little about you?

I think you are being negative saying you feel you might be a disappointment to him because of your difficulties. How do you know? if he was having trouble in his life would you think the same of him? I think you should leave it to him to make his own opinions of you, not guess what he may or may not think.
