Anxiety and shyness kick off around peers ?

I used to be that way except the opposite. I was okay around 1 or 2 people or 1 on 1 but around a crowd I was a total nightmare. You obviously need more self-confidence. Remind yourself that the people around you have their insecurities too, they just handle them differently. Don't be afraid to speak your beautiful voice. Don't be afraid to show them who you really are. You need to ask yourself what it is your really scared of. Look in the mirror and ask yourself that. You have something unique to offer this world and everyone should see it. You have a right to an opinion. You have a right to be who you are in front of others. Don't hold back. Speak your voice and when that voice of fear and doubt comes into your mind (" they think I'm awkward, stupid etc.) tell that voice.."yeah thanks for your opinion but I've got this". Everyone in this world is human just like you and everyone has fears. Face those fears. It takes practice but its easier than you may think. Good luck!
