Hi surfer,

Welcome to the NeuroTalk Support Groups.

You could try posting in
General Health Conditions & Rare Disorders Forum

There are many posts and thread regarding arachnoid cysts scattered in various different forums here.

You could find them by doing a full forum search with the link below
http://neurotalk.psychcentral.com/search.php

There is a
PTSD forum
here too although somewhat quiet.
Our sister site PsychCentral has a PTSD forum as well.
The link to that if you ever need it is at the top of the NeuroTalk PTSD forum.

I'm really sorry that you're dealing with this right now and your fears of surgery are understandable however keep trying to think of the positive outcomes once it is over.

take care there.
