Wendy,
I understand EXACTLY how you feel! :|
The very best thing I did was to enrol at my local college to do a photography course - we had to bring in new photos every week for the class to look at and discuss - terrifying to start with, but brilliant as you go on

it forces you to make sure you have something new every week - and to look at magazines & websites to learn new techniques.
we
all 'fed' off each others inspiration, drew on each others experience, and ALL grumbled about our tutor!
for me, it has been an unbelievably rewarding experience - I have learned SO much, been pushed out of my 'comfort zone', learned about other photographers techniques and emulated them, and I am now looking forward (ish!) to my first exhibition (along with my fellow students) next month
I have met some fabulous people - both on the course and on here, and I've learned never to pass up an opportunity to get out and take photos with like-minded people.
my advice to you is to get stuck in - find a course at your local college, meet up with the toggers here, look at famous photographers and see if you can emulate their styles.
The world is your oyster!!!!
