choices/questions/answers????

I have come to a point in my life where I am wondering what to do next.  my sole purpose in this world is to be a Mommy. A good Mommy. The bestest Mommy. and raise my 2 little people to lead fulfilling lives.  I am lucky in countless ways, and never forget to say thanks each night before going to bed.   That being said, I am so tired. Tired of HAVING to work (yes I know having a job, a wonderful job at that, is a blessing in these times), only to barely make ends meet, and at the end of the day have all 3 stooges sad and frustrated that Mommy has to go to work tomorrow.  I don't mean to sound ungrateful. I am simply fed up with missing my kids everyday. fed up with not having any help, and  having to choose between my life long dream of being Mommy, and bringing home the bacon.
Life is more blessed than cursed. I am well aware of our gift of everyday, whether it is unconventional or not is not the point.  Simply being here, together, loving and living, is the point, and the gift. 
I never thought I would become a single parent. nor did I ever think that my faith and morals and belief would be tested as deeply as it was, and continues to be, through the path I stumbled into having to choose between my sons, and the man I vowed to stick by.  I am humbled, and hurt, that I was not loved in return, and deeply wounded for my sons, to know that they are not loved by that same man. It breaks my heart each day, to know that while they are the 2 most precious beings in my world, I made such a bad decision in a partner for myself, and in many ways, the 3 of us pay for it, and will continue to do so, for many years to come.
I want to be a fulltime stay at home mom. The mom that my kids know will always be there, and their friends know they can rely on for backup when no one else is around.  I daycare 3 extra kids right now, and love it. I sincerely want to follow my ECE education and spend my heart and soul and energy on loving children.
Paycheques are for bills, spending and investments.  
I believe, with all my heart and soul, that the only worthy investment is in our children, for they are the only investment that gives back tenfold, whatever we choose to invest in their lives.

I need guidance, to find the path , the true path, for us 3Stooges.
