I don't know how long you have been moms and had to struggle with this, but whether you have been a mom for 15 years or 5 months, it just seems like there is always guilt for a mom.
Guilt about the the kids, the husband, the house, the job. Do men feel this guilt? No! because we feel enough guilt for everybody!
I have experienced years of guilt, and quite frankly, I am tired of it! I love my family with all my heart, but it is time I love myself a little, too.
What I have started to do is to prioritize what is important to me ,and work my way down.
Of course, my kids and husband are first.But,I am third. I am no longer going to stand in line behind the housework, the laundry or the cooking.If I don't feel like making my bed because I have something else to do, then by golly I am not going to make it! You know, there are other members in the house, who could pitch in and lend mom a hand!
After me is my job. I like to sometimes put my job right up there with me in line, because I like my job very much, and it makes me feel good when I have done a good job.
I want to throw in , though, that if I were able to stay home and make that my job, I would take it a little more seriously.Because, it is my job. But who said that house work always has to be the woman's job?
We women work just as hard to make money as anybody else. So, why should housework be a woman's job? Unless you are a single mom (been there, done that, got the t-shirt)and are responsible for everything,try to delegate the housework.And even as a single mom,depending on the age of your kids, you can delegate some house work then,as well.
I know I am rambling, but it pains me to see so many moms struggling with the guilt to get everything done, and feeling like they are on a treadmill.
You also might think I am full of it, but I like to think of myself as a liberated mom. My daughter is healthy, happy (except for the normal teenage moodiness)and we have a good relationship.And I am no longer driving myself crazy with guilt.

I just posted my first comment on Full TIme Frustrations titled Vent. Then I saw your comment! You summed it up I feel like i'm drowning in my own life! The life I wanted. My husband says those things too and then I feel guilty!

I don't know how working moms do it. I mean I'm doing it, but my husband tends to think I'm not doing anything out of the ordinary. Ok, maybe I'm not, but it is new to me. I have a 7 month old baby, and have never raised a baby before. I feel like I'm drowning in my own life. My husband says "your the mom and that's what mom's do". Really? Some days (not all) I wish I could run away.

I wish I had the magic answer. I ask the question everyday "how does everyone do this". I work in the office and at home and some days it just seems so not doable. My job seems so daunting and there are times when my to-do list there is longer then at home. I also feel that now that I have a child I am viewed differently since I can not always stay after or want to do the "happy hour" thing. I want to go home to my daughter.
