Final answer:
Melinda's problems in 'Speak' originate from being assaulted, leading to her social isolation, depression, and communication struggles. Lack of support exacerbates her situation, but she begins to heal through art and finding her voice.
Step-by-step explanation:
Melinda's problems in the novel Speak by Laurie Halse Anderson stem from a traumatic event that occurred before the start of the school year. Suffering in silence after being assaulted at a party, Melinda experiences social isolation, depression, and struggles with communication. These issues are compounded by the lack of support from her peers and the adults in her life, making it difficult for her to process and overcome her trauma.
Throughout the novel, Melinda's inward battle manifests in different ways, including her withdrawn behavior at school and her declining academic performance. It is only through art and slowly rebuilding her confidence and support system that Melinda starts to confront and address the root cause of her problems, leading to a path of healing and empowerment.
