I don't respond to light therapy

I started using my light therapy glasses late July early August, last week of August I had changes to mood, and ended up with very bad brain fog that persists, along with food carb cravings, and no energy or motivation.

Doesn't matter how much I use my light therapy glasses, Luminettee, I've tried a couple of different light boxes in the past, it just doesn't work in making me feel any better.

My moods fluctuate during spring summer time also

I have tried lots of different antidepressants, and they never really did much apart from side effects

My dad is bipolar. A shrink has told me on a few occasions over the years im not bipolar, but I don't respond to traditional therapies for SAD

Starting to think maybe I am bipolar
