I"m not srue I will ever be able to be on my own again.

My sister had a seizure. The first in 20 years. I was there when it happened it was quiet, she just froze and then for the next half an hour didn't seem to know who she was or what was going on around her. It came back as suddenly just as we were getting into the emergency ward. This happened the night before she was to have her meeting to decide how she is going to be cared for form now on without my parents in the home anymore.
I have been staying with her for the last 8 days, about 20 hours a day. She isn't a problem most of the time but I have little to no time of my own, to be alone, to be on the computer, etc... It is driving me batty and now she has a seizure.
I may not be able to come over even for a few hours a day anymore. I have only minutes now to post this. I want to cry and scream and haven't the time nor the place to do it. I can't in front of my sister or it will upset her.
I had just gotten good with my sister and planned to do more with her but now I can't look at her and not be in fear of her having another seizure. I am now anxious and afraid and trapped and still don't know what to do most of the time.
