Why don't you try something relaxing like Yoga or meditation - Yoga is great for teaching you how to control your breathing and focusing your mind. meditation is great for getting your fears and illogical worries under control, both will calm you and make it easier for you to cope with these changes.. There is also a brilliant book called "Feel the Fear and do it Anyway" by Susan Jeffers. And no disrespect to Sue, but please stay away from Drugs they will not help. Also try to avoid stimulants like tea, coffee, coke, chocolate and alcohol which will all add to the nervy feelings. Lots of Love - Amara xx
