Anyone experience seasonal affective disorder but from living somewhere hot all the time
Yes a million percent. I live in Texas and it's beat down brutal for months on end. Dry and hot. Crazy awful heat. Gets worse every year. Now there are winter droughts. No rain here for the last two months. Nothing. I have black out drapes and avoid light. Summer heat/sun related sad is very very real. More on reddit.com

[Serious] Those of you with Seasonal Affective Disorder, what are some tricks you use to overcome it as the days get shorter?
In Seattle 13 years, and battled with it every year. Cost me numerous relationships during that time... Nothing fixed it, but three things took the edge off: Full spectrum solar lamps. I had multiple. Vitamin D supplements and exercise. I choose indoor rock climbing. Frequent winter vacations to sunny places. All of my vacation and sick leave was spent during those dark months. In the end, I couldn't take it. I literally moved to Mexico yesterday. Today, because it's so warm and sunny, and I'm not fucking depressed and anxious, I took a three-hour nap. ... I never nap. I just feel happy here. More on reddit.com
