Baby separation anxiety

Hi everyone.

My baby’s separation anxiety started when she was 8 months old. She’s now 13 months old. She won’t go to anyone. Even her father. Whenever I leave the room or get up she starts crying and wants me. I can’t even give her to my family or anyone helping if I want to go to the toilet. I don’t know if this is normal but she’s in a very safe and healthy home so we does she act like this ??
