Serious attachment issues and it’s getting too much.

My little girl hates anyone that isn’t me. Including her father and it’s getting too much. Nobody can go near her or hold her except me without her having a complete meltdown. I can’t even leave the room for 2 minutes to use the toilet. My husband is really upset about it and says he doesn’t understand why his daughter hates him and at this point I don’t know what to say anymore. It’s draining for me and I’m very worried what’s going to happen when I have to go back to work in May as this girl seriously gets hysterical. Any advice would be fantastic as we cannot continue like this
