Hi Erika and welcome,
I’m sorry you are in a situation like this, that’s a lot to deal with 
It’s hard and I cannot imagine how hard to loose your partner. My condoleances.
You are in good hands now and I hope the physical damage can heal with the help of the care takers. Did the rehab provides you with some kind of aftercare?
I will share you a link where you will find recourses for recovery. Maybe you find something to add into your recovery.
I really hope you will see this place as a safe spot to share and ask for help when needed.
It helped me a lot to be here daily to keep myself acountable. I checked in every day on the daily check in thread. Maybe it’s useful for you too? Here you find it:Checking in daily to maintain focus #70 - #240 by Shel75
For now I wanna give you a big hug 
Be strong! You are stronger then you think you are! Do it for you and your little kid
