Not feeling excited for baby anymore

It's been a tough trimester. I've been horribly sick, and haven't been able to leave the house for 6 weeks. The past few days I've felt really depressed. Like I just don't want this baby. My body is changing and in so uncomfortable and anxious, and. Y entire life is going to change. The responsibility of caring for another life feels particularly overwhelming now. We planned this baby and I was so happy in the beginning, but I lost that feeling. I'm just miserable and overwhelmed now. Does/did anyone else ever feel this way?
