sounds like you're having post partum anxiety and stress. do you have family or a confinement nanny to support you during this new period?
babies cry as a way of communication, not that you are being incapable as a mother, have to remember that baby crying is just natural, not that it says anything about you and your ability to be a good mother.
it will be helpful to get support (husband, family, friends, or hire a nanny/maid) so you can have time to breathe and let someone else handle baby for you while you work through your anxiety
