What do i do????! 2 questions.. one about cookin and the other motivation?

ok im livin on my own, but can't make myself do anything. how can i push my self hard. to do homework to clean.. etc. also.. im a very bad cook. i know how to put things in the oven and boil but when it comes to cuttin, slicing, mashing.. or bein very creative i lack it. sometimes i get so unmotivated to cook cuz im so bad at it.. so i dont even eat....
