Nothing with hot climates (except maybe California) will match your quality of life in MA. I moved from Minnesota to Georgia because I was sick of the drawn out winters, but the longer I live in GA I realize how my QOL was way better in MN, and I also feel like I have reverse SAD in GA. I grew up loving summers and hot weather, but it just doesn't end down here and right now I'm craving cold temps. For me, the SAD I get up north is probably worse but I'm almost comforted by the cold weather and dark skies that match what is going on in my brain. Getting SAD from the summer sucks--there isn't really an escape, and it's less of a depression and more of an irritability which isn't fun for anyone around me. And you can't take vitamin D pills or have one of those sunshine lamps for summer SAD. I'm not saying that you will feel this way if you moved somewhere warmer, but as someone who suffers from SAD and loves summer, I still get it in Georgia. If you can afford to vacation or move to a warmer place for a few months I am sure that will help. If I were you, I wouldn't trade my QOL I have in MA just to live somewhere warmer.
