So I am on the spectrum and was diagnosed with GAD 6 months ago. I have been on a SSRI and Lamictal. Lamictal was slowly increased from 50mg to now 200 mg. It has helped me so far, I don't have emotional outbursts anymore (I used to have them to the point I wanted to claw my face off) and feel "normal". 

Now my issue was horrible nightmares every night, intense enough to cause me a headache or make me cry because it was so painful. It was till the point I couldn't get a decent night's rest. In response to that my doctor prescribed me Quetiapine. Whenever I take that I just fall asleep in 30 minutes with no dreams or nightmares whatsoever. Whenever I miss a day or two I end up having nightmares again.

I read Quetiapine is an atypical "anti-psychotic" now I am anxious if I have something more than GAD. And now I am even more scared that I will be dependent on medication for the rest of my life to just function normally. Another thing is whenever I am stressed I feel tremors in my head...which is weird.

Is it even normal for anti-psychotics and mood stabilizers to be prescribed for GAD? Anyone in the same boat?
