being a new mom

My son is only 1 day old and being a mom is already so tiring and difficult. I just love my son so much and it breaks my heart when he screams and I can't seem to make him stop, it breaks my heart when I feel like he's in pain or gassy, it breaks my heart when I feel like I don't know what to do or how to take care of him (I'm a first time mom). I just want to be his 'super mom' and take care of him and instantly know what to do. I just want the best for him and I feel like I'm not being a good mom when I can't get him to stop crying..or when I send him to the nursery (I'm still in the hospital).
