Summer and Winter SAD?

Is it possible to suffer from mild winter AND summer SAD? I have come to realize that I have patterns of about two times a year (winter and early summer months) when I feel agitated, sad, unsure about myself and my relationships, need for change, tiredness, ect. Thank you.

Hmm, I thought SAD was because of lack of sunlight, which is why it's usually associated with winter. I've never heard of it being in the summer. I guess a lot would depend on where you live and how much sunlight you get.
I can get a little depressed in the winter. I think a lot has to do with everything is dead, it's cold and little sunlight. I love the summer because all the flowers and trees are blooming.
I'm not sure why you only experience this twice a year. Have you tried getting out more and getting more exercise? That can do wonders to making you feel better.
Sorry if I wasn't much help. Best wishes.
