How to help stop shyness/low self esteem/blushing?

I am really shy and have really low self esteem. If I am talking to a teacher, I blush and fidget, and I can’t even say hi to my sister’s best friend without blushing. Here are my 3 Questions.

Unfortunately you can’t really stop the blushing. It’s a physiological response. You can stop being shy just by forcing yourself to go out and talk to people. I’m assuming you’re not really a conversationalist, so maybe think of some things to say to people, or just strike up a conversation and listen to what people have to say. You just have to kind of force yourself and everything will work out. And for the self-esteem, in my personal experience, I set small goals for myself and tried to reach them. A good final result is nice, but it’s the effort that boosts your self-esteem Ohhhhh and surround yourself with positive people. Don’t hang around Debbie Downer anymore.
