     We often face difficult times. It’s a part of life. And in these difficult

times, just stopping is not enough, and we need to ask for help.

     When I have a problem, I never go to a single person for help. In fact, I am lucky enough to have a strong support group. First, my parents are nice to

me. So when I’m faced with difficulty, my parents are usually the first ones I go to. Many of us don’t think our parents can understand us. However,

they have gone through situations(情况) as hard as or maybe even harder than those we go through today. So why not listen to them and learn from their

experiences(经验)?

     There are quite a few situations when we don’t want to ask our parents

for advice(建议). For these, we can turn to our friends. We can talk about our problems at school. It’s great to be able to receive the opinion of a

friend.

     Having problems is nothing to be ashamed of(难为情).When you need, go and ask for help, because the help of another can often get you through your

darkest times!
