Hello Truly,
As hard as it may be and I understand totally how hard this can be to do when nervous have a go at these sugestions.
Try and regulate your breathing. Difficult but achievable if you really concentrate. Breath in while counting slowly to five and let it out and count to eight or even ten if you can.
Do some positive thinking - tell yourself this is what you want to do. Tell yourself its a good thing and it wont take long. Try not to focus on the nervous symptoms your body is giving you such as the shakes and increased heart rate.
Think very hard on giving yourself a reward either for when you come out from the appointment or for tonight - hell, for both!! It could be to watch a favorite film, cook something yummy or have a take away. How about a deep filled bubble bath with some candles and a fav CD playing in the distance. It'l be your treat, your reward and need not cost much.
Good luch Truly, and please post how you get on
Julie
