Scared and confused

Hi,

I have a 11 month old plus an 8 and 10yo and a 24yo step son. Me and my bf had a really toxic unhealthy relationship (3yrs) up until I got pregnant with our baby. Since then weve been struggling to work on us and get past past traumas(1.5 yrs). Anyways. I just found out we are expecting again and Im so nervous and overwhelmed. I told my bff of 15yrs first thinking she'd help me feel better... She replied Gross, Good luck. I'm not sure how to take that. Like I know she knows all the crap my bf has put me threw and she hates him but damn. That hurt me. She is going threw alot of her own stuff. But I help her in everyway possible. I even work nights so I can stay home during the day to watch her kid. Just wanted to know what y'all thought. Or some words of encouragement please!
