Lots of why's

Why do I have low self esteem? Why did I not realize what I was doing? Why didn't I fix it? Why didn't I try better? Why do people have to tell me what I did wrong? Why did I found out now? Why was I not smart enough to know or listen? So many why's I don't even know what or how to do them or fix them or deal with my low self esteem! Any suggestions? I need so much prayer about my inner self and my self esteem it is crazy and it has got me to where I am at today. It is why I am alone and why I am going through what I am and I just want it to get better and I don't even know how to fix me.
