That overwhelming feeling

Besides having ADHD, and some depression thrown in there, why is it so friggin hard to get myself together, my bills, my home, every aspect of them. You know when you see people write how hard it is to do the simplest things, like im saying, you want to tell them ' well stop talking about it and just do it! Seems and sounds so easy, its the easiet solution, but i get it now. It is nowhere near easy, its like standing at the bottom of a huge hill , with a broken leg lol  Its so overwhelming , in my head, and then it gets worse b/c i avoid and less gets done, more to do. Its so hard to understand the feeling i get when i look at it all and know what i have to do. Its overwhelming, its scary, its unobtainable. I guess bc i really cant keep it great is that i find i clean up my stuff and more just accumulates. Its never ending and i dont help it with my shopping issues. lol, i buy way too much, stuff i already have, i just like it. Ill tell you one thing, its very hard to admit this to the world, i know it in my head , When i actually do accomplish stuff i feel so happy and so content and proud. I guess ill just try hard today. Its only one day at a  time anyway, isnt it....
