Stress after birth

My baby is already 2.5 months and i still struggle at times. There are good and bad times. Sometimes, i can tear while rocking my baby to sleep because i feel that i am not good enough to be his mum. When my baby cries, i might not know what he wants. My mil also did not render much help. She only came to play with baby once in a while. Never ask how we are coping. She used to say she will take care of him when we go back to work but then now she backed up last min leaving us to find alternative plans. Please seek your parents help. I regretted not going to them earlier. My parents came to help me after seeing how i am struggling. I used to be tough but i think hormonal changes is making me emotional. I keep telling myself to think positive and hopefully things will improve.
