Lactose Intolerance

About a month or two ago I found out I was Lactose Intolerant. Sucks really. I can't enjoy as many of the foods as I had before. I've tried soy, rice, and almond milk and I like them pretty well. But what about cheese and ice cream? Where can I buy dairy free cheese and ice cream. Or even butter? Also, does aged cheese really not have lactose in it? And what cheese would that be... Sorry for all the questions. Just not being able to eat dairy makes me sad :( Thanks for all your help!
