在一个遥远的森林里，有一个小精灵名叫梅丽。梅丽是一个活泼开朗的小精灵，总是乐于助人，但有时她的好心也常常让她感到非常生气。

一天，梅丽帮助了一只受伤的小鸟，它的翅膀被一根刺扎破了。虽然小鸟很感激，但它却没有及时谢谢梅丽，而是一直忙着找食物。这让梅丽感到很沮丧，她开始思考为什么自己的善举总是在别人的不经意间被忽视了。

第二天，梅丽又帮助了一位老树，因为风暴中的一块巨石差点儿砸碎了老树的皮肤。但当她回来查看时，却发现那位老树已经枯萎了，并且没有任何感激之情。这一次，梅里的怒火更大了。她觉得自己似乎什么都做错了，没有人会真正地感激她。

这次生气，让梅利意识到需要改变一下自己的做事方式。她开始练习一些放松技巧，比如深呼吸和冥想，这样可以帮助自己更快地恢复平静。当她的朋友们再次来向她求助时，她用一种更加积极的心态去面对问题。

有一天，一片黑色的乌云 suddenly appeared in the sky, it looked like it was going to rain. The animals in the forest were all worried, but Meli remained calm. She knew that she had learned something important - that her happiness shouldn't be dependent on others' gratitude.

So, when a big storm came and many animals were frightened and ran away, Meli stood tall and faced the wind with a smile. Her friends saw this and they realized that their small acts of kindness didn't have to be recognized by others in order to make them meaningful.

Meli's story teaches us that we don't need anyone else's approval or recognition for our actions to have value. What truly matters is how we choose to react when things don't go as planned or when people are ungrateful towards us. By learning how to manage our anger effectively, we can find inner peace even in difficult situations.

In conclusion, if you ever feel angry because someone doesn't appreciate your help or kindness remember Meli's story: your actions are valuable no matter what others do or say. Take some time out for yourself every day; practice relaxation techniques such as deep breathing exercises so you can handle any negative emotions more efficiently without letting them consume you completely!

And most importantly remember that life isn’t about seeking validation from other people but about finding joy within ourselves while doing good deeds!
