Hello and welcome to the NeuroTalk Support Groups.

I'm sorry that you're having such a difficult time. A number of issues you have mentioned in your post stand out to me.

ADD, Social Anxiety (managed to somewhat cope with after nearly 30 years), High IQ, noise sensitivity, irritation and anger etc..

I'm just going to throw out a few questions if you don't mind...

Do you take medications for your ADD or Anxiety?

Lots has changed since you were diagnosed when you were 7. Do you still see a Psychologist or anyone regarding your ADD and social anxiety? I guess you saw one a few years back for the testing (IQ etc)? You were never diagnosed with Asperger's Syndrome?

What is your B12 level do you know?
