I'm sorry for the trouble you're having. The only way to recover a hacked account is to follow the steps provided by Microsoft Support; https://support.microsoft.com/account-billing/how-to-recover-a-hacked-or-compromised-microsoft-account-24ca907d-bcdf-a44b-4656-47f0cd89c245
Unfortunately, if the above method doesn't work and the email address has been replaced by the hacker, you won't be able to recover it using the steps in the link, in which case I suggest using the Recovery Form.
If you are unable to complete the recovery form, you can try contacting Microsoft support, Follow these steps to chat: https://support.microsoft.com/home/contact
