Zues, the universe is motivating you to become a better person a lot faster than you were ready to, which is HARD but no reason to lose faith.
As a practical matter, I'm a full-time mom and I can tell you that having a plan (written is even better) for each day and each week makes everything a lot, lot easier. Asking for help where you need it is also crucial, and especially in the current circumstances people will be quick to give it so don't hesitate to ask. It's not weak or needy; people were meant to live in community. And great friendships can be born when you trust enough to ask for help.
Whatever kind of dad you've been in the past, that has to be in the past. From now you are a great dad. Think of yourself that way. It makes the job easier.
It's funny how people would think a suicide attempt could be a great healing event, isn't it? Yeah, not really. Don't give in to people like your mil. She's hurting and doesn't understand how her daughter could do this. Probably doesn't understand what came before either.
Praying for you, Zues.
