Absolutely! I used to be a doormat and finally got tired of it.
My mother a toxic control freak who is bipolar and doesn't take meds. She brainwashed me (easy to do to your children) and mentally ruined me, though I am now recovering from it after 30 years of it. As a result, I used to let other people control me as well.
I don't do that anymore, though it wasn't through therapy or reading, it was just real life and of course took much longer (hindsight is always 20/20).
I'm not the opposite (a control freak), just someone who refuses to allow other people to rip me off or try to control me. For example, one time the convenience store tried to jack me 20% on a cup of coffee (i.e., $1.19 instead of the advertised price of 99 cents). I refused to pay more and the stupid cashier (owner) refused to correct it, so I said no thanks then, I don't want the coffee. He banned me from the store! Fine, I wasn't going to come back anyway!
I have plenty other examples of getting rid of control freaks. They are like roaches. They need to be stomped on or sprayed with controlicide.
