Myself, Subconsciously Sick

I whine endlessly as if I have all the reasons to feel sick about life.
I am ungrateful for everything and it makes me hate myself.
I seek for the things I lack while I ignore those things I posses.
I am too lazy but I wish to succeed.
I am always anxious because I feed myself nightmares that I, myself, create.
I am always hurt because I expect too much and I wish my imagination is not that broad.

I do not actually know who I am.
