I am off work with the same symptoms. It turns out I have sleep apnea. I'm much better but still have trouble some days. At least I can took now. I had sever word finding problems

Snap!
Yes I always lose my train of thought when speaking as well! My emotions go up and down.
Ive just try not to get frustrated and be a good listener. Old Music I find lifts me a bit, playing guitar and being empathic towards others.
Sorry to hear about you not being all to write. I used to be in a band and found my depression drifted away! Then when gig finished the feelings returned....

Have you had a good psych eval. I was diagnosed with GAD & depression for years-- fair to poor results. I recently had a major manic and have been diagnosed with bipolar 2. Put on depakote still working on it but am feeling really good at times.

could I get refreed to a sleep analysis speciclaist through my GP then?

Get a sleep analysis done by a specialist just to find out if there isnt something that can be done. venaflaxin, makes me have very deep dreams, brilliant, I talk to my mum, my dad, mind you they are both dead. You feel so much better after a good nights sleep
