I'm a totally different person now... I want to be given a chance but it seems it these people might not forgive me.

I'll be happy to be your sounding board.

You put this under Parenting. Is there a parenting issue that hasn't been resolved? Who are "these people"?

What is it you have done. Who needs to forgive you? How are you a different person? And how long has it been going on?

It is possible to be forgiven for just about anything. But it takes a big heart to forgive someone, even bigger to forgive yourself.
