Hey omm,

 don't feel inferior, if u feel that u are inferior then the whole world will treat u in that way. Try to respect yourself and your presence. Being nervous during presentation is a common thing experienced by a lot of human. But learn from each task, never keep thinking deep about how nervous u were or are. Say to yourself that u will do better , coz noone's perfect.

 U gotta forget ur insecurity and overcome it. THere's a proverb >success is not in never falling bt raising every time u fall. So,  respect ur talents and ur presence, have faith in god and love who u are!
