Onlyfans will commoditize what your cousin is selling in short order, just like early adopters on Uber, Airbnb, Ebay, etc...the laws of supply and demand will only allow this to last a couple years, tops! Then what will she have learned and what skills and experiences will she have to be ready for the following two years? What skills and experiences will you have at that time? Easy come, easy go.

Also, "depressed," is different than, "discouraged." Careful of your word choice and make sure you are labeling your emotions correctly.
