Give yourself a new Voice to listen to - The Fighter
The Fighter is YOUR voice, it kicks the bully's butt, it reassures and relaxes Tweak, and it slaps a little backbone into the Defeatist
Your mind is a powerful tool, and it wants to work for you; sometimes it needs a little direction.
This is what you did when you had finally had enough and were tired of the others; just formally identify it as you have the others.
Congrats on taking back your own life
