Death in the family

I’m feeling really awful thinking about this but I have to tell someone because it’s eating me up about how bad I feel .... my SO his grandmother is getting off the ventilator tomorrow and we know she already isn’t going to make it, and his more like a mother to him, she raised him more then his mom..... But I can’t help but think of the death in the family and god giving us our miracle baby!! I know I’ve heard it before a death in the family and then you find out your pregnant it’s bad to say but I’m already praying this is it we get our baby and the sweet woman ain’t even passed yet, I feel terrible for even thinking this..... maybe it’s because we’ve been TTC for so long now? And it’s over taken me!
