PPD? Help..

I'm not sure if I would say I have ppd because I'm not depressed.. but i definitely feel overwhelmed. I'm very emotional and just feel alone at times. My baby is about to be 2 weeks on Thursday. My husband works 13 days on and 1 day off and 10 hr shifts.. its def hard and taking a toll on me. I also have a 7 year old and it's a struggle juggling baby, hw, dinner and bedtimes all alone. I feel horrible for feeling the way I feel sometimes, I just wish I had a little help and I'm really missing my husband with him not being home long enough to spend time with. Am I the only one? I didn't feel this way with my daughter..
