I miss the voice in my head
Why would you desire to keep the voice in your head?
I miss my little friend all the time who always tells me what to do.
Listening to the voice in your head without reasoning things through is a dangerous road to poor mental health. You need to get medical help and counseling and do it soon.
It's fine since the voice is gone now.
I guess that is fine. Was the voice from an early age? Sometimes people have imaginary friends when they are young so maybe this was harmless.
