date,anything
just write it, just write down on a paper everything
Take a step back and look at the bigger picture. and see this things as small,, see large picture of life-- and automatically why you are nervous is looking little
and tell yourself that everything happen for a reason,, and Whatever happens is for your good , that's why don't worry tell yourself, it might look silly but its all work
say this to your mind-- this is just a little part of my big life
pain = gain,, uncomfortable situation means benifit-- when you face this type of difficulties you became strong
talk to your friend and possibly talk to them who talk to you and motivate and encourage you
