Hi littlegirllost.
I can identify with just about everything that you say. I'm a few years older than you and many days I feel the same way about myself. I lost my mom at a young age and went through a lot of 'stuff'. It affected my self esteem, and it's been hard to get past. I feel sad for you when you call yourself a loser. Please don't believe that. You are raising a daughter...is that the image that you want her to learn from? You said that she's beautiful and smart, so you must be doing something right.

. Whenever I get down on myself, my husband always tells me "If you're not going to do something about it, don't complain" and that annoys me, but I know he's right, because if I don't put forth some sort of effort to change, then I will always be in the same place. Housewife's ideas sound like a good plan (I need to do some of those things for myself). Doing something that you enjoy can lift your spirits, like volunteering, a hobby, going to PTA meetings, continuing education classes, etc. And there's always counseling, if you need that extra nudge. You are not a loser! Change that to a positive phrase, like:
I am a loving person.
My strength comes from forgiveness of those who hurt me.
I am worthy of love.
I am free to be myself.
The more I love, the more that love is returned to me.
Love endures all things.
I am responsible for my life and always maintain the power I need to be positive and have joy.
I have the power to choose good things for myself in every moment
I am in control of my health and wellness.
...or whatever other positive thought comes to mind.
Take care.
