The marriage is only a part of your life. You have you to rebuild. You have the chance to become the best you you can be. It really is a gift. I know it does not seem like it, but it is. Go for a walk, go some place in the wild and just let your feelings out. Scream from the top of your lungs, take a baseball bat to the trash can, vent it out. We've all been there, it does get better, trust me.
Besides that, you have your S, he needs a role model in his life. You have to be the best friggin' dad in the world for him.
