Thing is though when you're the only one needing the support in the role...maybe the problem is you. One show off I'd still think is crazy, but at least more understandable. 2 is just problematic
I'd have more sympathy if it wasn't for the fact she boasts about her lack of training, has numerous times shown how she doesn't take care of her voice etc. So much of this seems self inflicted.
This is her second lead role and she basically isn't up to being lead physically and vocally. Heathers pushed her and she damaged her voice. All roles before it were supporting with one big song.
If she is finding it mentally tough then this is probably the first slice of the real world she has got in her entire life
