I would guess if any strain would be worse for anxiety it would have to be a high sativa, something with a visual high or really heart pumping. Even at that it would most likely only give a novice smoker anxiety if they smoked more than they can handle.

Sticky Fruit is a great bud for anxiety but also keeping a productive motivation with a sleepy come down.

Juicy Fruit....insomnia

I had Early Girl x Skunk #1 when i was in a moderate depression and gave a very happy relaxing plateau high, however it is one of those strains where you get higher and higher the more you smoke and eventually you will pass out where ever you sit. LOVE IT!
