I'm hearing voice am I going crazy or getting hardening of the arteries?

Talk to a pro. Sometimes, people hear the voices of loved ones when they are under a lot of emotional stress or in other situations, for example, thinking you hear the voice of a recently deceased loved one. Other times, random voices can be telling you to do things or that you are worthless, etc. Sometimes they seem helpful. Either way, a skilled therapist or psychiatrist can probably help you a lot!
