Child too much like me...

I have three daughters. One daughter is so much like me that it scares me.  She is very, very shy, unable to make friends easily because of her shyness. She speaks her mind at times that could come off judgmental and hurtful. She is so uncomfortable with herself that she doesn't know what to say when around people and can't seem to see how wonderful and great she is. Because of our financial issues, we were unable to "celebrate" her birthday the way I wanted to. Of course, she says that it was okay ,which really means I want to feel special Mom, but again I get nothing.  See it is hard to know what she really feels because like me, she never wants to put pressure on people.  She never wants us to feel bad that she can't get this or that. She never wants to be a burden and sacrifices herself so many times. She has to constantly give up things because of our situation, but rarely does she tell us. What really hurts is deep down I know as her mother I passed that on to her. When I wanted children, I never wanted them to feel like they were a burden, I always wanted them to feel special and know that they are loved. Too many times when I was growing up I never felt I was wanted or loved. I was left alone unlimited amount of hours on all days, including the major holidays. History has repeated itself and I left her home alone today. Yes, I had appointments that I had to go to for my other child, then I had to go to the store, etc.; all good reasons, right? I still left her home alone. I wanted to break the cycle, but all I did was add another clink to the chain....
