Amazing, You just described ME. I feel exactly the same way, I can't motivate myself to do anything and I sleep so much that it makes me sick. I don't know if your a person that likes the outdoors but It helps to just sit outside in the fresh air for a while. I read a helpful though somewhere that helped me maybe it will help you..
it read to start small and things will come together. or something of that sort. I took from it to do a little bit of the work or things that you want to get done and it eventually you'll find that it gets finished. Getting motivated to start them is hard because we think of the entire project and think its too mch to handle right now. Just think of a small part to complete and hopefully it will get you going...
