I had an amazing life but I threw it all away
How did you throw away your life?
I was a wicked person and did what I wanted.
Yes, I'm afraid that by acting in a wicked manner and only thinking of oneself, someone could easily end up throwing their life away.  If you drive away friends and loved ones, it could end badly for you, but you can still recover.
Cute.
I hope that you don't disagree.  You had a great life once, so you must have been doing something right.  All you have to do is work on being more compassionate and attentive to others, and they will recognize the good person they used to know.
