My account was NOT hacked but I was prompted to make my security info current, now I am locked out for 30 days. I NEED my email. Do I have any options?

I just got a new laptop with Windows 8. Under the User Account folder, there was a "trust this computer" option. When I decided to take that offer, I was guided to a verification page which had a telephone number from years ago which is no longer active. I changed the number, received a verification code by text, then discovered, apparently, that I would not be able to access my account for 30 days from today. I cannot log into my email account and I am expecting some very important emails. I normally check them multiple times throughout any given day. Does anyone know of any option I have that would allow me to access my emails now? 30 days is just unacceptable and will cause me serious grief. Please help. I'll check on this often. Thanks in advance!
