Unfamiliar ground

I used to know who I was once, but now I am not so sure. There was a time when I even believed I had figured out what I was and my purpose in life, but I guess I was wrong. I have fallen so far from everything I was and gotten so far from everything I thought that I wanted. Others around me look at me and do not see me anymore. I am not what I once was and I do not think I ever will be again. There is a part of me that wants to fight so bad for everything I believe I could be. Then there is that part of me that just wants to roll over and die. I saw a light once but the mirage faded and I was left in the dark on an unfamiliar ground. I do not know what to do or where to go from here.
