Final answer:
Raquel would benefit from therapy or counseling, particularly cognitive-behavioral therapy (CBT), to help her manage her emotions and improve her self-perception.
Step-by-step explanation:
Raquel's tendency to get extremely upset if she does not get her way and her belief that it reflects her future failure suggest that she may be experiencing issues related to emotional regulation and self-esteem.
She would likely benefit from therapy or counseling to help her understand and manage her emotions better and to challenge and change her negative beliefs about herself.
Cognitive-behavioral therapy (CBT) could be particularly helpful in teaching Raquel coping strategies and helping her develop a more realistic and positive self-perception.
