oh my giddy god

Tonight I've had a major attack of the wobbles,giggles, and a huge panic over the fact that in 10 days time i'll be getting married...the day itself i'm looking forward to, it's just the actual wedding ceremony i'm in a blind state of panic about...up until tonight i was feeling calm and not at all worried about it...but..h2b told me he was so excited and looking forward to it then asked me if i had any regrets/worries/concerns...well that was when it hit me...i feel sick, not at the thought of being married...but it's getting through the actual ceremony that bothers me..firstly i CANNOT cope with the idea that people will be looking at me, and secondly I know that I will wet my sides laughing (out of nerves) throughout the ceremony...I have this horrendous nervous laugh and have had bollockings from managers about laughing inappropriately during meetings..I've even laughed when my children have hurt themselves and when my son was admitted to high dependency after having an asthma attack...how on earth do people cope in situations like this..I know i'm not the first to feel nervous and I know i won't be the last, but what gets people through, and how do you manage?..?
