Family doesn't know..

Breanna • Tucson
So... my boyfriend and u are going through some hard times and have recently moved into separate houses. We have an almost 5 month old baby girl .. and shortly after the loving situation separation we found out that I am pregnant again. (We conceived about a week before the separation) I am living with my family (and our daughter), he is living on his own.. :( I am about 9 weeks along our second child is due around our daughter's first birthday. I know my family would be upset if they found out I was expecting again. I don't know what to do. Thank goodness I don't show early at all.. like not until after 25 weeks.. but I'm scared of their reaction. My mom is constantly saying I don't need to get pregnant and if we pass by maternity clothes or baby shower announcements she always says something like "we won't ever need those again".. I'm feeling very alone and lost right now. I'm terrified that the stress will lead to unhealthy circumstances for our child... aye...!!! What to do.. :( I'm due November 29th 2017.
