postpartum depression

Lacey
Any mom's out there with PPD? My daughter is 13 months old and for the past few months I haven't been feeling myself. More recently I haven't been able to control my moods at all, I get so irritated in matter of seconds over the littlest things. The sound of my baby crying is literally like nails on a chalkboard, it's awful and I can't stand it. I haven't been diagnosed but I'm pretty sure I have it. Does medication seriously help? Is there any natural remedies for it? I feel like I'm failing as a parent sometimes and more often as a spouse, who also is at the butt end of my moodiness :(
