Being a twin mom

The other day I had another twin mom ask me for advice on how to handle...well everything. It took me days to write her back because I dont want to make it worse for her but I dont want to lie to her either. So I told her the truth, her twins are one and mine are 3 1/2, and I told her it doesnt get any easier, it only gets harder. I struggle everyday with being a mom a wife and trying to just figure out who I am and what I am supposed to be doing. Am I good enough? Am I doing enough? Who am I? What can I do to help my children grow up to be kind, smart, and find their dreams? What are my dreams, where is life going? Im 27 now and I still havent figured out life, let alone how to manage 3 year old twins and 5 year old, plus a marriage....She just really got me to thinking....who am I and what can I and how do I find myself so I can make my marriage better and help my children to grow to be wonderful people....
