Whilst I agree that positive thinking in all aspects of life is preferable, there was nothing wrong with your original name Tammy, a username is your choice, unless it is obviously spam or offensive as Anthony mentioned. Your original name was definitely not offensive, I am sorry you felt the need to change it. Please do not be concerned about others being uncomfortable, the point of this forum is rather the opposite; if someone is uncomfortable, it means they are triggered and need to work on that aspect of themselves. It is not your issue, it is theirs.
