Am I a bad mother??

Please ladies don't judge. I'm beating myself up over this. Don't need negative comments. So I go back to work on 2-3. I have been exclusively BF my baby boy who is almost 7 weeks. I have attempted pumping but feel that it is not enough. He will be going to a very trusted person while I'm at work. But I feel horrible that she may have to supplement during the day. I will literally be less than 5 minutes away and I'm planning on going during my lunch to feed him. I also plan on BF on the weekends. How can I feel better about this and not stress??
