What happened to my life?

Why do I face this kind of situation now?

I think I have made a wrong decision three years before.

Even I did not make a wrong decision, things did not go in the correct way.

So, can I try to make all of the things in the correct way?

If not, and I also can not make a decision again.

So, what can I do now?

Can I have other decision?

Is there any chance for my life?
