Am I a bad parent

I'm about 10 weeks 4 days with baby number 2. My son is only 6 months old. I know it's soon to have another. Everything was fine and normal till a couple days ago. I don't know what exactly happened I just started feeling really down. I have no interest in taking care of my son. I do anyway I just don't want to. He's teething and constantly upset and some days just screams for no reason. Lately I find that any loud noise makes my ears ring and I just want to run and hide. It's causing problems with my marriage as well. Anyway. Am I a bad parent for not being interested in my child? He just feels like alot now.
