text: Yes, I'm always like that ever since I can remember and I'm pretty young too. Even if you sit at a desk all day it's enough stress to make you completely exhausted. I usually take a short nap after work, if I have enough time. One thing I noticed that helped me is drinking plenty of water, watching what I eat, and exercising. Your diet is one of the most important things though. You would be AMAZED at how different you feel just by eliminating processed and sugary fat stuff and eating more raw natural fruits and veggies. Also too much caffeine can make you burn out at the end of the day. Of course if you notice that your way too tired and this has come on suddenly you should make an appoinment to see your doctor. I don't mean to scare you but you could have other problems.
