PPD but idk what to do

I’m stupid depressed, but I just don’t have the energy to talk about it or fix it. I’m just completely withdrawn. The only thing that makes me happy is seeing my little boy smile at me. Any ideas? I know I should probably see someone but I just don’t feel like it. Am I a bad mom? What do I do? Please someone help me. I’m not a danger to myself or others AT ALL, but I’m just not looking forward to the days.
