It sounds like you may have clicked a Habit button a bunch of times and wound up with a lot more gold and XP than you earned, since clicking rewards spends your gold rather than gives it to you. (Don't worry, you're not the first person to do that.  :) )

Regardless, the Fix Character Values screen allows you to set any of your character progress stats (Health, Mana, Experience, Gold, Level, and Perfect Day Streaks) to whatever you think you were at before your clicking spree; that way you can keep your tasks and rewards that you defined.

Using the Reset Account option will set your account to be as if you'd never logged into Habitica before at all, so you'd have to really start from scratch!
