I pulled out and quit a great opportunity again?

I had passed a test that had over 500 applicants, and had moved onto the interview stage. I had been told the time, address and date and went in today. At the front gate there was 3 men maintaining a hole in the grass, maybe the pipes or electrical system. One of the guys looked like a leader, and there was 2 under him. They were interviewing me already it had seemed and I followed the hand written signs to the interview. In the room there was a few papers on a desk, so I asked the lady where was the interview being held and she pointed at the desk and I said ok. I was reading through the health thing and a few other people walked passed and assessed me. After 20 seconds I stood and left the room.

I walk out and can feel the few eyes wondering what I am doing. The guys at the gate all look up and wonder what I am doing and as I walk out the gate one of the workers cars bangs into the concrete as he is driving out. I walk to my car and there is a guy in a black car parked next to mine as if he was monitoring. I get in my car and he drives and changes his cars parking position and gets a good look at my face. I drive off and leave the oppurtunity.

I broke up with two girls that loved me, I've left a prestigious school I had a scholarship at, I have turned down multiple jobs and friendships. I live in my room and workout occasionally. I am over six feet tall and attractive. What's wrong with me.
