Hello Kiana,
Welcome to SR! It does sound like you have been through quite a bit with your sister, and it must have been frightening and exhausting. I'm glad your sister is receiving the care she needs.
How are you? Have you been able to talk to a therapist about the terror you lived through being locked in your room until the, er, storm passed?
I hope you will feel free to come here and vent or talk anytime you need to.
HG
