英文小作文：

If we look at our lives, we will find that there are always challenges and obstacles that we have to face. But for the support of our family and friends, we might not have been able to overcome them. However, we must remember that we are not alone in this journey and we should always be grateful for the help we receive from others.

On the other hand, we should not rely too much on others because we also need to learn to rely on ourselves and be strong enough to face any challenge that comes our way. In conclusion, we should always remember that there are always people who care about us and support us, even when we are going through difficult times.
