PPD - anyone else?

So my baby is a week old today. After her second day her daddy started his two jobs back. I understand he is working a lot so I don't have to right now. He leaves before we're awake and gets home late having to go to sleep within an hour.  I feel so lucky and blessed to be able to spend this quality time with my child but I feel so sad. I cry everyday, especially when he leaves for work. I feel selfish letting him know I'm sad because I know it makes him feel guilty not being around. For someone who doesn't cry often at all, this is weird for me. I feel lonely and I feel like being clingy could eventually get annoying. I know he's there for me and he's very supportive but my emotions are seriously OUT OF WHACK. Any advice or moms feeling the same way?
