miserable and depressed

I am 5 weeks postpartum and I am miserable. My baby boy was 9lbs 3pz when he was born and I'm still in a lot of pain. He is a good baby. Not colicky he eats every 3 hours but I am miserable. I hate my life. Nothing makes me happy anymore. I just want to fall asleep and not wake up. Nothing makes me happy and I hate my new life as a mom. I feed him and hold him and change him and sing to him and snuggle him so he will be happy but I would really give anything to go back to my life before him. I talked to my doctor and she wants me to talk to a therapist. I'm just so tired of feeling that way.  Is it just me ?
