What she can do as a hexenbiest isn't the problem. If it were, she wouldn't have given up the suppression potion to the scoobies in the first place. She would have found another way to help them, like telling them what Kenneth was up to.
Instead she calls attention to her hexenbiest spirit by developing this potion to suppress it. She immediately takes the potion to prove that the biest can be suppressed. Yet after that, she never takes steps to develop some kind of magic spell or potion that could rid her of her hexenbiest forever.
So either Adalind figured there was no way out, and she was always going to be terrified of how she thought and felt as a hexenbiest.
Or, she was lying to Rosalee.

The best way to frustrate a cyberbully is to ignore him.
