I am due to go to my 7 year old son's leaving assembly when he moves from infants to juniors. I am finding that I am getting upset and tearful at just about everything away from work. I really want to go to the assembly but am afraid that I will make a complete idiot of myself. I know that a lot of mums will be a bit emotional but I will be sobbing and not able to control it. What can I do apart from wear very large darkened glasses.
