I don't know what to do

My fiancé and I are living with my mother and brother. We live in this house rent free because it's covered in mold and should honestly have been condemned decades ago. I don't have a job because of how pregnant I am and the only one working is my fiancé. My brother is in his 30's and lives entirely off of my mother who only makes $50 a week. My fiancé and I need to move into a place that isn't toxic to a newborn but it's practically impossible with both of us having evictions on our record. As the due date gets closer and closer I can't help but feel like the best thing for my child is to give her to someone else and I can't bear the thought of that. I don't know what to do. My fiance works so hard to keep us afloat and I know he wouldn't be okay with giving up our daughter. I can't stand this. I'm already on Medicaid and food stamps because of not having a job. I just feel hopeless.
