My account was hacked!!!!!

last night I got a messege I need to re-enter my password I tried and it didn't worked..tried to restore via my email and it also didn't worked.. today I saw that someone deleted all my friends and groups and played today.. lest night I opened a ticket at steam but I don't know what else I can do.. the only reason I'm still connected here is because I wasn't asked to log in since it happened.. I'm afried I'll get VAC banned before I'll get my account back.. any advices?
