Deep from within

Today I had nothing to say, so I thought of sharing my personal self from within. Growing up I was taught to be the mature one, the bravest and understanding one since I was the oldest. I have always kept everything to my self never having to share my feelings. This has affected me greatly, often afraid of expression, rejection and explaining myself to others why I have done so. Often I can't say what o I want, ignore what I don't need. I realised that things don't work out if you don't say a word, you never achieve anything without a word. I would love to help many people but often I can't say a word. I want to change many things. I want to express myself better. I want to change my community. I want to be part of conversations. I want my voice to be heard!!!  Help me change myself to the best version I can be!!! How do I get rid of shyness?!!! How do I become a public person?!!!
