As does this.
If you feel the need to discuss these issues, boards specifically setup for your issues are a better place to have constructive conversations.
Further, I was an extremely shy child, to the extent that I almost had to repeat kindergarten because the teacher literally thought I was a moron because I couldn't make myself speak out in front of class for any reason, including saying "here" at roll in the morning. I worked myself from this debilitating condition via band and chorus. I found a peer group inside those programs. I can still have moments of extreme shyness to this day. I work on it all the time through community activism.
Some of my children had the same issue and solved it in the same manner via their own interests.
No one can do it for you and you can't solve sitting on a computer.
