something that causes harm or unhappiness
bane - curse
Something that causes harm, destruction, or misery can be referred to as a ‘bane’. However, the word is most commonly used for affect in order to refer to something that really isn’t that bad, but can sometimes feel as if it is.

Drugs are the bane of that underprivileged area. They have destroyed the local community.
My boss is the bane of my life. She makes everyday at work a misery for me.
