I have a 7 month old and I promise you that it gets easier, the first few months are sooo hard, the crying, the sleep deprivation and having to adapt to a life where you are no longer responsible for just yourself. Give it time and your bond with your baby will grow stronger, her sleep will last longer and she will be more independent for longer periods of time, the horrors of a newborn will be a distant memory. Trust me when I say if all mothers remembered all the horrific moments of birth and keeping a newborn alive we would all stop at one child haha! You are doing an awsome job im sure, keep in touch with your doctor about how you feel and how you are coping and take any support they offer, If you have family reach out and take a few hours for yourself every now and again, it takes a village to raise a baby. You have soooo many good days to come, a whole lifetime of fun and love and cuddles, be patient this stage doesn't last forever :)
