Motivation

Something I struggle with a lot is motivation. How do you make yourself do things when you'd honestly just rather be asleep?
You don't want to get up to eat, don't want to see anyone or do anything (even the fun stuff) but lay there and be as close to death as you can get; by sleeping.
As I yawn away I wonder if there is a reason behind this. Is it my medication? Is it my depression?
All I gt from professionals is 'the more you do the easier it gets' but I don't want to do anything that's the entire point! I really just do not see the point in doing anything anymore.
I started to write this in a hope to figure out what was going on in my head, but I can't even find the energy to care about this. 
I just want to fade out of existence.
