Help Dolly's Sister Visit Her in Hospice

The woman in the middle is my sister we call her Dolly. Right now she is very sick. I was preparing for this time to go to go see her unfortunately I was hit with some unexpected expenses I was not able to get around. I'm asking for your help to see her as she getting ready for hospice care. My plane ticket is 400 round trip bus is 360 I want to stay at least a week there so this is why I came up with this total. I'm on social security and the job I work part time we haven't because they have updating the computers and we don't get paid if we are unable to work but I'm running out of time and really could use your help. Thank you in advance ☺️
