Hi i have depression and bpd, i am also incredibly overweight but since ive been losing more and more weight the effects of low energy while upright have been getting significantly worse and my GP and mental health doctor are stumped. im 21 male i dont have sleep apnea but struggle to sleep and have restless leg. While vertical either sitting or walking around i am so exhausted i struggle to stay awake even if i drink coffee or anything typically used to boost energy it has next to no effect and has only been getting worse since losing weight, i currently weigh 155 kgs ive lost 45 so far. How ever when i lie down in bed i have next to infinite energy it seems and feels like. Ive changed antidepressants between the categories and no difference between them. I am not sure what to do or even if its normal but experts are stumped and makes getting my weight down and improving my mental health a real struggle.
