I have been in a toxic relationship and I hate who I have become because of it.
Why do you feel this way about yourself?
I got cheated on by a person who destroyed me and turned my life into hell. Now I'm weaker, sadder, lonelier and more desperate than ever.
What you've gone through is really difficult but you mustn't hate yourself because of it. Now you must work to rebuild yourself and get back on a good path in life.
It's easy to say that. I'm definitely going to get back at him.
Please don't. I think you could benefit from some therapy to work out why you want to be treated this way.
