I accept your decision, and wish you the best. But I think you are making a mistake. Just because a few wronged you, it doesnt stand to reason that you should cut off the rest. It is like amputating a whole leg for an infected toenail.
There are still many of us here who genuinely like you, and would be happy if you were able to stay, but as I said it is your opinion and I respect it. farewell, and good luck
