     We are most often called upon to support others in friendship. Several years ago, Donna had

been feeling very depressed(沮丧的). She had just broken up with her boyfriend of two years,

and she was having a very difficult time accepting the loss. She had been laid up with a knee injury

for several days, and the time alone at home certainly was not helping. Her misery(可怜)was only

increased by her being discouraged at herself for not being able to cheer up and stop crying all the

time.

     Early one morning Donna received a phone call with some terrible news: her best friend's brother

had been killed in a car accident. Donna had known this friend, Mary, and her brother nearly her

entire life, and the news was shocking. However, Donna quickly pulled herself together, got in the

car, and drove to her friend's house to be there with her.

     Over the course of the next few days, when attending the funeral(葬礼) and receiving the hundreds

of visitors, Donna was 100 percent present for Mary. She held her close while she cried her endless

tears, sat by her side as the waves of sadness washed over her friend, and slept on the floor next to

Mary's bed to make sure she did not wake up alone in the middle of the night. During that time she

felt hardly any pain in her knee at all and none of the depression she had been experiencing.

     Several weeks later, when life began to return to normal, Donna realized that the level of support

she had given. Mary had been far greater than any support she had offered herself during her dark

time. She was able to use the support she had given her friend as a mirror for the support she had

been holding back from herself. She realized that her own tears required as much care and attention

from her as anyone else's, and that if she could give it to another, she must be able to give it to herself,

too.
