Single mom to my two month old daughter. Need some positive energy.

Recently escaped domestic abuse from a narcissistic man and am left with my two month old daughter. I got a 3 year PFA and still have to do the custody case which I have SO much evidence of the abuse that I'm actually really lucky it will be a solid full custody to me and legitimate charges/jail time for him. The abuse was horrendous.

But I find myself still really happy and then really low, too. Just at the end of the day when I'm burnt. She is doing great and this subreddit came up "Walk away from your baby" when I was crying into my voice search "is it okay to leave my daughter alone for ten minutes while I breathe and she's crying after I tried everything or will I ruin her trust and mental health for the future" basically. And now I'm in the bath and it only took her 5 minutes to fall asleep without me.

Just looking for words of support. Advice, wisdom. My family support is equally as exhausting and I have every mean to cut that out as they equally do not respect my wishes and are lying often, causing more drama with theirs, but I'm so tired :( ...
