post partum depression and or anxiety help!! pleas answe

I'm worried..I'm 6 months PP and since about Christmas I haven't been myself. The thing is, there's been a lot of stress in my house. My parents and brother having issues, my husband has been laid off work for 3 months so we're both at home living on 1/2 our total income, our 6m old daughter has been cranky and teething. It's just been stressful. But it seems like 50% of the time I'm just slipping away. Maybe it's the winter blues? I just feel so down. And my feet are always cold and clammy. I feel like like my heart races and I just have lots of anxiety. Like I said how would I know if it's PP or just normal anxiety?? Will it just go away? I feel like it's not Pp because she's 6 months old..that would be weird. Does it sound like it might be? Like I said I have just as many good days as bad...so I really can't tell
