Feel like a bad mom/wife

I feel like a horrible mom and wife. And tonight it came to a head. My husband works hard. He owns his own HVAC business. I’m a stay at home mom and we have a two year old daughter and I’m 10 weeks pregnant. For a while now I’ve been stuck in this rut of just constantly sitting on the couch. I feel awful because I know I haven’t been doing what I need to do as a mom to play and stimulate my daughter. I also haven’t been keeping up with the dishes and laundry. Idk I just feel so unmotivated to do anything. I feel like I’m failing as a mom especially. I love my baby so much, but I just don’t know what to do a lot of the time. I feel like I’m useless. And I know only I can change it.

I’m scared for another baby, I’m scared I won’t be good enough. Like how am I going to take care of another baby when I can’t even do what I’m supposed to be doing now. Of course my daughter is well fed and has an amazing home life, I guess I’m just stuck on not getting out with her more.

Has anyone else ever been in a similar situation?

Please leave some words of encouragement because I really need it right now.
