Im soo scared..

So I’m currently 6 weeks pregnant I have a baby that’ll be two in November and a 5 year old. How did you guys get it all done?? I’m so scared that I won’t be able to handle it. I’m already overwhelmed with two I can’t imagine 3. We weren’t planning for baby #3 I was on birth control and my husband was using condoms. He keeps saying everything will be okay but it’s so hard to think that I’ll be okay. I feel like a bad mother because I’m not excited about this baby I’m just so scared.
