Is it normal?

Is it normal to cry daily the first weeks of having a baby? I'm not sure if I'm getting depressed or just regular stressed and tired. But every night I get sad and cry. It's better when my husband's home but I have the baby 90% of the time which is fine. I'm so tired and he's only 11 days old. I just wanna rest. My c section incision is still healing and I just need rest so badly.
