With the good side, comes the bad, there are things that make you happy, followed by things that make you sad, there are people who will accept you as you are, then there are those who doubt you and make you wonder who you really are.
Bad memories are like scars, sometimes they can make you try to change who you are, but you shouldn't allow them too because they ae a part of you.
Bad memories can affect you in many ways, the way you act, the person you are, they can go too deep and hit you hard, so stop them before they get in too far, because if you left them, you could and up forgetting who you really are.
