A question for my fellow watchers

Do you feel like you're stuck in a rut of regret and guilt, view yourselves lowly because you don't like yourself for who you are, and/or feel like that because of bad things you might have done to people they were close to?
This is for those who've answered yes:
You may find yourselves in situations like that, and can feel a lot of other things too, including the feeling of wanting to make up for your mistakes as much as you can.
We're only human, and nobody is perfect, so everybody has their own experiences with the "live and let learn" situation.
However, some people's situations may be tougher than others, and even with the purest form of sincerity used, there can still be grudges held against you if you find yourself in a situation like that.
It may be possible win everyone back, but the truth is that you don't have to win every single person back that you've had troubles with. Why?
Because even if you can win just about everyone back, you may or may not realize that the majority of the people are actually toxic, in the sense that they're just don't make you feel as happy to be around compared to others, even if you hadn't screwed up with them at all.
You should only attempt to win back the ones who can actually put a smile on your face, from when you first met them, all the way to the present.
When I last attempted to win people from my past back last year, it was a success, and I thought that my conscience my clean.
But as the months went on until around October, something inside of me grew to the point whereas I wanted to isolate myself from just about everyone.
I was confused, uncertain about who I wanted in my life, and almost thought things would go back to square one.
But then as the first months of 2014 started, I had an epiphany: That this is a new year, with new opportunities, and as I'm growing older, I should start living my own life for myself, and that I don't need to have anymore toxic people surrounding me, whenever they're from the past or the present.
From there on, I started to take out the trash, slowly pushing away a lot of those people, and the more I did it, the less I would feel bad afterwards.
I did things I never thought I would have the balls to do before, and became a different, more better kind of person in my own eyes, not caring about how the other eyes view the new me.
So really, if you don't like the way you are now, or feel like the current you is making you and others around you feel too shitty, then you can change.
You can be whoever you want and forget about who you were, especially if you feel who you were causes nothing but pain upon yourself and those close to you.
Life is all about evolving and changing; Some people may change drastically, others may change only in little bits, or some will just stay the same for the rest of their lives.
Remember that as you're reading this, this is the mind and body that you have been given, but it doesn't mean that it has to stay the same forever.
Don't be afraid to give yourself a new face, a new personality and a new sense of identity.
Be whoever and whatever makes you feel the happiest and the most self-confident, and then afterwards, you'll begin to feel an intense rush of freedom that you may have never felt before.
And if anyone toxic from your past tries to drag you back into the world of bullshit and grudge holding, push them away like that you never knew them in your life.
They have no places for the new you that you could be, and to the new you that you could be, they're just strangers who have mistaken you for somebody else that doesn't exist anymore.
I promise you that if you do this, you could never feel any sense of regret or guilt over the things you've done again.
You'll be as free as a bird, and if anyone stands in your way, you'll have the power to take them out without a care in the world.
