When dealing with depression or anxiety or any other mental illness, oftentimes people will experience issues with sleep. Sleep is really important for our development and growth. Oftentimes people think, oh, when I'm sleeping, my brain turns off. It's actually the exact opposite. While you sleep, your brain processes everything you've learned over the course of the day. If you don't get that sleep, you haven't learned whatever it is happened during that day. Sleep can be restorative. It can provide you with energy as well as a clear mind to tackle the next day. One thing that can be difficult when dealing with mental illness is that either you get too much or too little sleep. Both of these can actually be difficult and problematic.
