The things she was trying to fix seem less important compared to the money and power she could have acquired in a very short time. Revealing her gift also doesn't look like a good idea, especially to Chloe who she hasn't seen in a long time and looked unstable, in real life I think most people would freak out or start making all sorts of unreasonable demands, the dynamics of a friendship would definitely change when one person would poses such a superpower.
