Fruit - too much?

Options
I basically live off of fruit. Since I'm a picky eater, I get most of my health from fruit. I do get lots of protein from meat, fish, greek yogurt, etc. But I don't eat a lot of veggies that often. Is this bad? I mean, I've lost 7 pounds and I can exercise efficently and do everything with energy. I'm pretty sure I get most of my nutrients, too. But is too much fruit bad for me? Thanks!
