About

I did not have the confidence to ask questions, and I was embarrassed to ask questions.

I have an identity problem, and I do not know who or what I am. I feel I have no place among human beings. Of course, I still do not have the courage to ask my questions. I confess that I'm afraid to be ridiculed. I feel that by raising my knowledge, I can find a good identity.

Help me, if you can. If you can not, pass me by.
