To the OP- I tried to email you through Gmail and it bounced back to me. I talked with Alan this morning and he doesn't know how to get ahold of you or your mother via phone.
I didn't want to overly concern him, but I did relay to him what you posted in your original post-that she was quite sick and missed him. Please provide different contact information or preferably a phone number. I know that he cannot travel right now. Like I said, his phone number is not working at this very moment but 512-701-0918 is his phone number. I believe you can leave a message, but I don't think he checks them very often. Really your best bet is to call my mobile number 650-454-4275 and I can transfer the call.

PS- I post under quite a few aliases. JoeBiz JoeBiz99 on Lambopower, FerrariChat, Lamborghini Forum, CMRA, BARF, RRW, WERA, etc. I didn't know that I should verify my identity prior to posting. I guess I thought a phone number would be sufficient, I'm not that hard to authenticate. My apologies to the forum if I wasn't following protocol!
