My concern with this story are her self-professed, life-long mental health issues. The context (from the various articles I read about this story) screams cries for help. As such, her parents showing unconditional support may actually be harmful.*
If she were a (mental health) client of mine I would encourage her to explore a wide range of issues surrounding this announcement. Because my "fear" is that this will not end well for her (and thus, her family).
*There is a well-known dynamic in mental health counseling where people try to show support, but the support actually harms. For example, "minimizing" substance abuse as something that will pass, overlooking self-harming behaviors by terming it alternative lifestyle choices, giving in to the eating habits of anorexics by rationalizing that doing so will help these sufferers regain control over their lives (etc.) all fall under the "when helping hurts/helping harms" rubric.
As written, these various stories show that Mikaela is not being well-served by those around her.
