Ouch! Is that new-ish? I have a recollection of people going inactive for longer than 3-4 months and returning.
Sigh.
Unfortunately, I believe you'll have to make a new account.
Look at the bright side: a whole new story for you to write has just appeared. Your family? A sudden disease knocked it out... A single man or woman (Your favorite character or whatnot) has started a new name. Or... MAYBE not a disease, but your family was murdered and you switched names to save your remnants.
There's always the possibility of using your old name, no one will judge for doing so.
