Major Mom anxiety?

My little one is turning four months old tomorrow. As she is getting older, the conversation of moving her to her own room is becoming a topic between her father and I. he wants to move her as soon as she turns six months. Before she was born, I would have probably agreed with this. But now that she’s here, I have this crippling anxiety of our house catching on fire and the thought of her being in another room terrifies me. It’s ridiculous I know, but the what if’s kill me. I would like to wait until she is at least a year old, but I know no matter how old she is, it’s not going to change the fact that I have this crippling fear. I imagine it in my head over and over again and it makes me literally sick. We live in a 2400 square-foot home, and our bedroom is on one end of the house, and her nursery is on the opposite end. Do any other mom’s deal with this? Is this normal or do I need help? How do I get past this irrational fear? I know I can’t keep her in our bedroom forever, but I don’t know if my fear will ever allow me to put her in her own room until she’s way older… 😭😭😭😭
