I found once I started to sleep through the night everything got so much better. Sleep deprivation is just terrible, lack of sleep keeps emotions and logic a scrambled mess. I am very glad to hear you are sleeping well.
I understand your feelings on being a single parent and faking it. Nice to see that you are making it and are experiencing genuine gratitude and joy.
Btw I remember very well your encouraging words months ago about all the things I still had to be grateful for. Thanks.
I hope Mothers Day and dinner goes well. I think it is great that your W wants to spend time and do some activities with you and the kids.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
