Need some encouragement

My narcissistic ex husband to be has been in rehab for a year. I am fighting for supervised visits. And full custody. This weekend is our first supervised visitation. It will be at my house and my mom is the supervisor. Im really struggling with it. but for some reasons I guess because it's the first times he's coming back into the picture. Like it's finally happening. He's going to be at my house. And they time hes getting is on the time im off of work. So i feel like im not getting much time with them. I just need some words of encouragement to se the bright sides. Or just help get through the next month as this is temporary. Our custody court case is in March. Please no hate. First time going through this and just want freedom from his emotional and verbal abuse. He lied to the judge and that's making it hard too.
