Today my diagnosis notes arrived in the post. I've never been given the option to have notes sent out before but this is actually pretty handy as A: I have something solid and real in front of me that could help calm me down in that I know that this is definitely a real thing that is happening to me and I'm not just being weak willed.
They also have a more detailed diagnosis than my doctor was able to give in person or that the doctor who called was able to give me over the phone.
While they agree that I have severe anxiety, they've both decided that I'm a low risk of being a danger to myself or others (which is at least something good right?), and that I should take a course on stress management to see if it helps me with dealing with panic attacks.
Unfortunatly it looks like I won't be able to join the programme until after Christmas (no room for me at the moment), so I have to try and work out how to cope on my own for the stressiest possible time of the year for me :/
