I'm so glad you saw your psychologist and that you have said yes to going to this hospital. I understand that you are scared, but you need to be somewhere safe and I don't think this place is going to be any scarier than your current situation.
I hope they won't bully you into any treatment you don't want (I know you don't want to be medicated), but I do think you need to be completely honest with them. They can't help you unless they know everything that's been happening to you.
You're in my thoughts, eden.
