Having been through many different types of abuse through my childhood, I know the feeling. Sometimes in life you have to face what you fear the most even when you don't want to.
When I refused to face what had happened to me, it sent me down a long and dark hole that took me ages to get out of. Thankfully, after many therapy sessions I learned to cope with what had happened and that most of all, it's never your fault.
Don't be scared of what may or may not happen. When life deals you a deck of cards, you can only play with what you have.
Hope your appointment goes well, and don't resign. It's only running away. =)
