The quote from Gail Honeyman's book "Eleanor Oliphant Is Completely Fine" reflects the protagonist's realization about the importance of companionship in overcoming struggles. Having tried to face her difficulties in solitude, she acknowledges that this has not been beneficial for her. It speaks to the universal truth that, at times, everyone's challenges can feel overwhelming, and sharing those burdens with a supportive person can provide comfort and healing.

This insight emphasizes the need for human connection and kindness in difficult moments. It highlights that while isolation may feel like a way to cope, reaching out to someone who cares can make a significant difference in managing emotional turmoil. Hence, Eleanor's journey illustrates the impact of companionship and the strength found in vulnerability when dealing with life's challenges.
