Hey! I'm very sorry to hear about your hacked steam account. Unfortunately we can't do much for you ourselves. You should contact the Steam Support as soon as possible to recover your account. You should be able to get it back fairly quickly after proving your account ownership. This article on the steam support page should help you: help.steampowered.com/en/faqs/view/0A94-F308-34A5-1988
If you have any more questions or issues with your account, don't hesitate to contact us on discord.
