I can't take it anymore

I can't take it anymore Iam 25M currently pursuing b.ed course and as you all know.. b.ed course is full of presentation and its taking a heavy toll on me to get laughed at every presentation session because my face gets distorted when i struggle to speak and just the fact that it will continue till 2 year session is pulling me into a depth of despair...i don't even know what i want by posting this but ..how can i cope?
