Welcome back Farmboy!
My therapy progressed to the point that I went from lying down all the time to being in a wheelchair to using a walker to trying using a cane.
When I had one foot in a body bag a couple of years ago I declined from walking to a cane, walker, wheelchair in weeks and likewise recovered along the same path once I started to get better.
Situations like you describe are why some of my primary domains are paid years in advance to avoid losing them under any circumstances. My personal domain that all my accounts are tied to was originally prepaid 15 years.
Never rely solely on an ISP account as ISPs can go belly up or even completely change things and you can come back and find yourself in trouble.
I fully recommend a dedicated email address, and relying on Yahoo mail or GMail can also be a major mistake because you could get locked out and nobody there to help you get back in, just like Farmboy is having happen.
I have the whole family on my domain and we've been using these email addresses for a good 18 years now so they would be motivated to keep them going in case I got sick again, or worse.
Besides just getting sick, natural disasters like earthquakes, tornadoes, floods and fire can put you in just as much risk of losing it all which is why I have a backup of my websites and passwords sitting in a flash drive keychain, my cell phone, tablet, and netbook. I assume the keychain and phone will be in my pants, if I get time to put them on, as I run out of a burning or collapsing building.
I also have SSH and FTP software on my cell phone and tablet so I can administer my servers from the smartphone at a minimum. Can't do a whole bunch in a hurry without a Bluetooth keyboard, but I've been able to fix emergencies from anywhere.
Additionally, use cloud storage, you can put encrypted files in Drop Box, One Drive or even email them the GMail, etc. so you have other places to recover your stuff if you need to do it.
Farmboy's message is important, but for more reasons that in the event of your sudden or near demise, you just need emergency backups, access, multiple email accounts assigned to your AdSense account and register your cell phone as primary contact which I've done.
Also, all of your accounts should1 be auto-billing off a credit card or directly from your checking account. I have all of my bills set to automatic payment and I'm pretty sure everything would keep going at least a year without my intervention unless the worst happens, the CC company cancels a card for security reasons which they do all too often causing me lots of grief. This led me to use one card for paying bills vs. another card for my personal usage as keeping them separate lowers the risk of a card number change for security reasons.
The problem is people will read this thread and go "oh poor farmboy" and be in denial that anything like this could ever happen to them.
Eventually, something happens to EVERYONE, health issues, disaster or even DEATH. So if you don't take away the need for preparedness, don't go crying to someone when you get caught with your accounts down as you've been thoroughly warned to be prepared.
