Insult

I am awful...I am abandoned...I am unwanted...

But u can't avoid me, u can't refuse me,

I will come irrespective of who you are!

I am like the subject of History in school.

No one loves me but you still have to face me.

I am that distasteful medicine no one wishes to have me but can't avoid it.

I will come to teach you a lesson!

I am like engine oil.

Use me wisely and reach heights!

But Misuse can ruin you!

Who am I?

 I am "The Insult".
