How do i recover my steam password if i don't know the secret question?

i want to play Terraria but i forgot my steam password so i tried to recover it, but when they sent me an email with the verification code they also sent me my verification question that i put in when i made the account, the problem is that i don't remember the answer, it asked for my school name and i put it but that did not work so i probably made something stupid for it. so how can i get the password back without having to know the answer to the question, i really don't want to have to buy Terraria again.
