How to increase my confidence?

You were beaten because they only wants what's best for you. You should be grateful, not all have the chance of having someone to make her understand things while they were young. Try to read and understand the events in a positive manner. You proved many things because you are tough and prepared. you are aware of what you want and knows no mistake. Just be yourself and everything will be fine.

That is why one should not scold kids for good things if they do. I think because you were scolded, that is why you have this problem of lack of self confidence. Just be positive and think that whatever you know and are going to speak is going to be appreciated and people are gonna like you. You are the best. There is nothing that can stop you from being what you want to be, have what you want to have. Thanks for sharing and have a wonderful day ahead.
