Meltdowns Meltdowns Meltdowns

Chloe, my daughter, has just been in meltdown mode for the past 2 days. Everything we do just does not help. She just seems 'stuck', if you know what I mean? 

Long story short: 

Chloe went out for the afternoon, came home to 100's of spiders in her bedroom, on the ceiling and walls. We got rid of them all but she did not want to sleep in her room which was understandable so slept in with her sister. 

The next day, some spiders came back, and she refused to sleep in there again. We have got rid of them again today but she is still refusing to step foot in her room. 

She just seems stuck and frozen now. She doesn't know what to do with herself. The tears and meltdowns are constant. She is refusing to eat, shower, do anything and all she is doing is pacing. 

What can we do? 

Thanks, 

Lucy
