good question! the state of sleeplessness is what every mother goes through. sleeplessness can cause depression,moreover the pregnancy hormones may still be present in the body up to the extend of up to 4 months n this may also result in mood fluctuations like anger,extreme sorrow,tension for silly matters etc....
feeding a one month baby is a real concern coz u have to wake up at night in every 2 hrs to feed the baby....sacrifice ur sleep fr d baby up to 3 months coz it may wakeup n cry every 2 hrs in order to be fed....its quite common....

stay calm and be patient..this is a very natural tendency.
try to remain positive as your positivity will help your baby too.
everyone of us have problems...dealing with them is much more challenging especially after delivery but we as mothers have to come out strong as we have to bring up our baby
