Help!! I can’t access my hotmail account and thus, can’t get to my e-mails!!

I am currently unable to access my hotmail account and I am concerned that this is because someone has hacked onto it. My password is no longer allowing me access to my hotmail account and because it is used for important things such as work, I am desperate to regain access to my account and access my e-mails. I attempted to complete an online task to retrieve my hotmail address, however I was told at the end that I didn't provide enough information to be sent a new password to access my account and I would need to wait 24 hours (despite answering my security question correctly). Because of my concerns that someone else has gained control of my account and is using it to send junk mail to my friends, I have had to create 2 new email address and let people know not to send emails to the hotmail account I can't currently access and to send future messages to one of my new hotmail accounts. Please help!!
