Sweetie sounds like you are doing it pretty tough. Every bub is different and Fraser is just finding his place. The girl at MG doesn't sound very nice, especially if they asked you to leave when you obviously needed some support.
Talk to your doctor of health nurse because it sounds like you need a bit more support for yourself. If you are struggling he will pick up on it and it will affect him (I have PND and I know when things are really bad Mr P responds to it)
