You are by no means a pu**y for expressing fears and anxieties.
It takes a real man to do that, and to press forward and battle on. There are all kinds of situations that are scary, this will be around all of us until the grave. It's how you/we deal with it that matters.
You are battling, big time, with addiction, anxiety, your child going to kindergarten, finances, etc.
But you ARE battling, you haven't just quit and gone back to drugs and alcohol.
Keep fighting, the payoff will be so worth it to you and your family!
