3rd kid on the way

Please don’t get me wrong, I’m sorry excited but I’m also terrified. I have a 3yo and 1yo and am 10 weeks along. I’m just so scared. It’s already so hard 😔 I wanted 3 but just a little further apart. I’m also scared because I think I’ll have to stay home and I am not meant for that. I work part time and some days that I’m home I miss work because I feel like I can’t do anything right. In October my 3yo daughter just had a complete personality change (and I know she is going through a lot of growing and development stuff) but some days my patience is done. I manage not to scream which I’m thankful for, but it makes me depressed. I just need some encouragement... I’m just a mix of emotions right now.
