Seeking help.... advice.... something........

I am suffering from postpartum depression and I went to my doctor today and he prescribed me Wellbutrin. I started it tonight but he says it will take weeks for it to start to take effect.  Any other mommies out there going through or have gone through this???? It's something bad and all I have done is apologize to my husband and kids over and over for letting it get this bad... anything helps and I was told it helps to talk about it.... so here I go.
