This is a difficult question and one I've struggled with. I don't regret having my wonderful children, but in my darkest moments I fantasize about what life would be like if I were childless. Its not really fair to put all the pressure and fault on you to make a decision. Every parent needs a community and support whether you have one child or six. It was never meant to be done alone. As a mother with mental health issues I dont know what I would have done without my husbands or parents support at the darkest times. What qualities are you afraid will limit your ability to cope? When the children are babies its hard on parents physically due to exhaustion. As they get older that part is easier but there are other issues and challenges. What concerns you specifically? You cant really imagine how your world changes when you have kids until you have them. It will be important to have other resources and support for your husbands illness during the early years bcuz babies require so much care. Just some thoughts.
