I hope that you have found everyones answer has made you feel more positive knowing that most people feel that awful feeling of isolation and feeling lonely.
I must echo what some members have said about not restricting yourself to just people of your own age. My son is at University and his friends still come round to visit me and I also go out with my daughters friends and she is 22! Although I have never been to an EF event I am going to make the effort this year and travel up north. They sound like GREAT fun and the nice thing is that the age range is very varied,

So - I SHALL SEE YOU THERE
