My health has deteriorated along with my mind. I've gained ~30lbs (male) putting me on the edge of a 30 BMI, but honestly it takes so much effort to focus on weight when I'm already suffering in mood and sleep. I'm trying to solve one thing at a time, and I assume sleep is at the root of all of my issues. My depression medications also tend to cause weight gain, which doesn't help. Diet wise, I eat relatively healthy compared to most of the US, but that isn't really saying much. Obviously I'm consuming more calories than necessary, hence my weight gain, but I believe it's more portion sizes than anything else.
