Feeling down... Any advice???

Shanny
So baby is 3weeks today, I have been EBF and already the changes in my breast are depressing. My right side is tremendously smaller than the other and both seem a little droopy. I know that this is good for baby but this is stressing me out. I feel like my milk isn't enough ... I losing too much weight too fast . So annoyed.... Words of encouragement , ideas anything would help right now. Smh
