S.L.
There's always a silver lining, and a reason to be grateful, even if it's not apparent at first. I'll give you a reason to be thankful that you're going back to work. And that reason is that you could be me instead!
I can very clearly imagine the pain you must be going through. I have 3 boys, one in school, one preschooler, and one toddler. It would be like ripping my heart out if I had to stop being their stay-at-home mom. But it also rips my heart out every day that my boys and I have to stay in this awful family situation because I don't have a career to go back to, or a job that I can get to support my boys. I don't know why you are getting divorced, but I'm so glad that you CAN get divorced and move on to a happier life with your girls. Me? I'm trapped. And trapped is a bad way to feel.
I'm in therapy, too, and it really does help. I hope you find some peace and inner strength from it. I don't know if men feel the same way, but women, I think, always have a hard time with the unknown. I'm scared, and I'm sure you are, too, but I see you moving toward brighter days. Things will work out, and you and your girls will find happiness.
