St Johns Wort

Has anyone taken St. John's wort while nursing? 
I'm not taking anything else at the moment and I really hate the thought of taking anti depressants. But I need to take something to feel better because I am miserable. I've been having such a hard time lately between my PPD, anxiety, having to move with my 6 week old, having no help from family, and just found out we are going to owe the IRS money when we file our taxes. I wasn't expecting that. 
I am extremely stressed and I feel so depressed.
Anyway, back to my original question, does anyone know if it's ok to take St. John's wort while breast feeding?
