fragmented sleep, insomnia, tingling/numbness in toes, fingers, tongue; painful feet, hungry all the time, general shitty feeling all the time
Fragmented sleep, insomnia, feeling shitty... those are all signs of depression and anxiety.
Hungry all the time... that can be a result of the medications you take. Most psych meds make you crave carbs or sugars.
Tingling/numbness in toes, etc... that can be a sign of a disc problem in your lower back. I don't know your weight, but higher the weight and the more you don't stretch and stay in one place or sit a lot can lead to disc problems. I'd get this one checked out soon, or go to the hospital if you get flop feet where it just drops without your control. You can get irreversible damage when that happens if you don't get it treated.
Painful feet... that can be from the above disc problem too, or some kind of pressure foot sprain.
From the above i would be able to assume (i don't mean to be rude or anything) that you are overweight and do not exercise or move around too much. Exercise can really help all of the above, and same with eating healthy.
Everything i'm telling you is from experience of what happened to me... for i had all of the above in the past. As soon as i started eating healthy, going to the gym, most all of the symptoms above are now gone. So, i can tell you this works from my experience if you do have similar issues. I also take a medication that makes me crave sugars and carbs, but now i eat mainly a veggie / meat diet and that alone is very filling so i don't crave anything else, and if i do... i can eat it here and there bc i exercise. That's why both exercise and eating healthy are so effective. Plus, if you push yourself when you exercise... to your limit, the amount of endorphins your body releases is like taking drug. It's easier said than done however, i understand that... but the better you can do this yourself, the better you'll feel for a host of reasons. I never believed it would work until i said screw it... i'm sick of feeling like crap. It's a mindset.
