Hello Toast,
Welcome to the NeuroTalk Support Groups.
This forum is fairly quiet I'm sorry, but I hope someone familiar with Colloid Cyst will drop by and see your message.
I'm really sorry you're dealing with so much at such a young age.
There may be info. in some of the older posts.
You can do a forum search for keywords.
