Postpartum depression?

I’m 4 weeks postpartum and im honestly just not feeling myself. I find myself feeling alone and crying a lot. I have a support system but it’s hard to talk to them about this kind of thing. I have a hard time finding the energy to even make food or shower, when baby is sleeping I’m either sleeping or just want to watch tv and relax. I’m exhausted and overwhelmed... I’m not sure if it’s just exhaustion from have a new baby combined with hormones or if I should be worried. Anyone else experience this?
