Being shy and bashful

I am an 18 year old boy. I m 5ft 7inch tall. I got a strong muscular body and I am a very active boy. The problem starts when I am in school. I feel so shy that I can't even participate in different activities. Can't give my opinion in debates. Can't ask the miss a question if the class is quiet. Can't play sports because I think what others may say about me and I am a very timid boy in school. My friends are boys and I can't even mix up with them too. Socially my worth is nothing. Sometimes I look at people who are not good like me (I am not being proud but I am just saying) even they are confident and make the class lively. Please help me out with this. Sometimes I feel so sad and depressed that I don't have many friends because of shyness and can't do what I want to do. Shyness has cost me a lot. Please send me a dua or something which will make me confident and will boost my self esteem. I don't like talking to girls neither I want nor I will but I can't even ask them about homework or just anything about studies or anything related to studies. I feel like my face is ugly so people don't want to talk to me and my friend often tells me that I got a handsome face. Its not about the face but when no one talks to me I feel like isolated and weird. Please help me.
