Answer:
In The Metamorphosis, the main character Gregor Samsa faces several obstacles after he transforms into a giant insect.
First, he is unable to communicate with his family, who are horrified by his transformation. Second, he is unable to move around easily, and his new body makes it difficult for him to perform normal tasks. Third, his family is disgusted by his appearance and begins to neglect him, leaving him alone for long periods of time. Finally, his boss and coworkers come to his house to check on him, and he is forced to hide from them in order to avoid being seen.
All of these obstacles make it difficult for Samsa to navigate his new life as an insect, and he struggles to find a way to communicate with his family and come to terms with his new existence.
