Hi Pixie, and welcome!
You have a lot on your plate, by the sound of it. Single working parent is a tough job at the best of times -- so many demands and it's really hard to find even a second to do something nice for yourself. My girls are 12 & 14 now, so I'm starting to regain time for me, but I've long ago forgotten what it's like even to go to the bathroom with the door closed.
You've come to a good place. As Sylvie said, keep going on the program and post here whenever you like. The combined wisdom of this group is wonderful -- I'd be surprised if there's a situation or issue that at least one of us hasn't experienced. And sharing your experiences helps us all, so again, welcome!
