Concerned about ppd.

Fairly certain I've got a case of the baby blues...and I'm just not sure how to deal with it. I'm 12 days pp and I have no motivation to do anything except what needs done for my son. I take care of him (so does the hubby so I've got plenty of help) but other than that I literally just want to sit around and cry. It takes me an hour to work up the energy and motivation just to take a shower and eat. My mom keeps trying to get me to come out to lunch or something with her thinking that may cheer me up, but honestly, I don't even want to deal with people at the moment, which is a whole other ordeal because I have a huge wonderful loving family that wants to see the baby and I have no desire to interact with anyone outside of my husband and son. I've called and spoke with my doctor, she says it's normal but I definitely don't think this extent is normal. I just want to get back to being my social self and it doesn't seem like my body wants to cooperate. Should I get a second opinion or just wait it out?
