am i over-reacting

i joined a web page .this web page shares people's experiences .i liked it firstly .i have shared my feelings ,my thoughts and my experiences .but i didn't want to share my name , my region , my nationamity with people to keep my self anonymous so no one would juge me as a known person .
Firstly i started communicating with people in this website . In a conversation , a lady started talking about religious things , i made a mistake when i told her that i read the bible when she asked me if i do .though i'm muslim i said "yes , i read bible !" stupidly .i am an idiot because i thought that all holly books are called bible .when i came back again to the website i found out that she left me a message on the whiteboard saying : read some parts of the bible like psalms as i remember .i was shocked i didn't know what to say to her .so i told her that i was wrong and that i'm muslim .it was an embarassing moment for me .the worst is that i sent her this message in publuic .so everyone knows that i'm muslim and it's not good for me because i thought that when people know that i'm muslim they would judge me and neglect me because of my bad experiences that i wrote in my profile .i thought that i'll bring for them a bad idea about muslims and islam that's why i found it hard to communicate with people after what happened .and i think that the lady was upset with me or feeling that she was talking all the time to an idiot .
Desperately when i knew that i'm known i shared my name and my nationality too which made me perfectly known .
so now , i'm afraid to talk to this website's people .and i wish i wasn't talking to them . i became so hesitated when i talk to them and frustrated too .
what can i do ???!!!!!

It is very difficult to share ourselves, in person and often, on websites. It is a good idea to know yourself and who you are and what you want and be friends with yourself first. I would take this experience as a learning experience for yourself and not worry so much about being judged or think so badly about yourself. It sounds like you made a mistake, not understanding the subject; English is not your first language? Do not be so hard on yourself or worry so much about what others think of you. If the woman is ignorant and does not realize you may have had difficulties with the language or concepts, that is her difficulty, not yours.

I agree with Perna, try not to worry so much about others' opinion of you. That is something that is outside of your control. Perhaps you can ask a moderator to remove the post that contained your name?
