Choices.....we all have them to make. Little ones and big ones. The wrong ones can hurt us and can hurt the people that we love. The right ones can be hard, but make life worth it. I think that we know the negative things that we do and choices that we make, and that we have the power within ourselves to make positive choices. I have been trying to do just that. It is really hard. But it is all worth it. I don't want to do anything that hurts myself or my husband. Sometimes I think that I am riding that line....and I don't want to hurt my husband, because it is not intentional. Sometimes I need help or someone to lean on, and that is all ok. I try to be so strong, but sometimes I feel like the weakest person alive. I have had my world fall down around me recently and things are settling out. I am so glad. I want things to progress quickly and I have to keep telling myself to be patient. 
You know I'm around if you want a shoulder.
But, I completely agree with you that we have the power to make the right choices. We can (and must) do what we can to make ourselves happy.
