25NL Stars - fold AQo preflop to 3bet all-in and call: standard?

[The Mayo]

I have no reads on either opponent, but I just can't see myself having the needed equity to play, so I folded. I was obviously push/fold here. Is a fold standard, or too nitty? (I tend to play scared, and I'm trying to fix that.) As an additional question, what range should I be willing to go with here?
