I am in a similiar situation though my two older ones are in school all day and the 19 month old is home with me. I am in grad school and work part-time; though those hours are never set as I work in the counseling field w/regards to domestic violence and abuse. I have NO ONE to help me. All my girlfriends are back in the workforce and my schedule it tight, very tight. Add to that an child w/special needs and, well, stress is too common.
For me, understanding that I made this choice is very important. That it is also very important to my children helps me too. I walk early in the morning and I take the baby everywhere I go. True "alone time" is not part of my life; but nor is it for DH. When he comes home, I have to hit the books or go to classes or work. We are a team and we MUST work together or else.
I guess I really don't have any answers.

I have good days, bad days and horrible days; we all do, if we're honest with ourselves and each other. Know that you are not alone, know that you are doing, I believe, the MOST important job there is. And know (as I'm sure you do) that this time will SPEED by; too quickly (not that it seems that way when things are going wrong though, lol). Enjoy the little things; watching life through the eyes of your child. A bubble bath. A cuddle with them on a cold, rainy night. Going for a walk.... alone. Reading during a nap.
I do want to add this: don't worry about the dust bunnies. Don't worry about the house being spotless. When I finally (and it was HARD!!!!) stopped needing my home to look perfect, life got better FAST. I can either do this...... or clean. "This" may be a one time thing, but cleaning the house will ALWAYS be there. It helped, it really did.
Hugs to you. Hugs to us all!
