Could I be suffering postpartum depression

Hi, I know this is a question for

Medical professionals but I want an opinion before I seek help because I’m so overwhelmed. I have a healthy baby boy thank god.

There’s always so much to do and he’s such a mommy’s boy all he wants to do is be carried fed and put to sleep by me only. Nobody else. And not to mention he’s teething so he wakes up frequently. He’s never been good with naps so he’ll

Or whenever he stops crying. All I ever want to do is catch up on housework or rest. I’m not even interested in romance with my husband nothing.

I feel so bad for complaining but I can’t help it sometimes I have thoughts of not being here it’s just too much sometimes. Maybe I am weak minded but I need help
