It absolutely sucks. I don't turn 18 until the very end of July, and almost all of my friends are now 18. They have ID, they can get into clubs easily, and I find it particularly hard. I, and a few others, end up getting IDed and our 'friends' just waltz off into the clubs and leave us to amuse ourselves. It's really frustrating. Especially when you go out in a big group, psych yourselves up for a brilliant night out, and then you have to go home whilst everyone else has a good time.
How does everyone else deal with this? Fake ID's look laughably fake. It's difficult to find an 18-year-old who looks like you, whose ID you can borrow.
