why you have that kind of thoughts? take it easy, I can understand where you come from, I have no more free time of my own but I think it's still happy to have a baby.... don't you feel happy when she/he smiles to you? With that, I think it worth everything....
don't worry too much, time will take care of things, no matter you are happy or not, time will pass the same way... but you have a choice whether to live in a happy way
