Don't give up on fighting to see your children, jamielow.
Your children will understand that you've been sick, and that you do love them dearly. You just have to hold onto that reminder and get help, to get you through this very rough patch away from your children. Perhaps you qualify for some sort of assistance to help you work through what is supposed to be done next.
Gentle hugs to you. Please stay safe for your children. They do love you!
