im not saying it will, but with a chance of being close im gonna quickly throw in my two cents
negative thoughts are okay, because negative things do exists in life. There is no point to be positive all the time, that is the same as living in a disney story. As cliche as it might seem I come to AO to get my mind of these stuff, just enough to realize there's still good stuff in life. Also write down your thoughts, use an online journal or paper as a way for you to let out steam.
But it's best to have an mature friend, count it ONE, that you can absolutely trust with talking to them about different issues you might have.
