I'm sorry I've only just seen your post
I hope your low mood lifts soon. Do you think you will turn to ADs for the winter. I think you said you were thinking of it. If they work i think I would go for it. I find winter a very difficult time. SAD is a chemical imbalance but I suspect there's a large psychological component with me.
I have been thinking in a manner that is really bad for me ie imagining my life will always be like this and imagining the decades ahead. It suddenly occurred to me last week to measure it in much smaller chunks. This is definitely helping. It's too early for the pregabalin to work yet. Time will tell
