The one thing I've been dealing with my SAD is that it always comes back. When It's gone life is amazing. People flock towards me cause my positive side is that great (Not trying to sound douchey or cocky at all lol) but everything is just enjoyable and people are great. But so far it seems to always come back after an amount of time. Something always sparks it back even though I know in my head it's not worth it. It's the worst feeling ever knowing "Here goes another week or two until it passes again...".
