I’m having bad postpartum depression. Help!!!!

I just had my son a little over 3 weeks and I love him so much, but I hate these thoughts in my head. I would never harm my baby and thinking like that makes me think that I’m a bad mother. My son wakes me up throughout the night for feeding or to change his diaper. Around 5 Am he won’t go back to sleep and the only time I and him would get some sleep if I hold him in my arms while sleeping on the couch. It’s uncomfortable, but at least we both get some sleep. I hate having to get up out of my sleep, but I do it because of my baby. I know I won’t act on the thoughts in my head and I just want them to go away. Have any of y’all felt this way before?
