Grudge
It is something that I don't purposely wanna hold to someone, holding a grudge is something really tiring, but at the same time very hard to let go. It makes me get annoyed at the smallest things and quirks from a person that I usually wouldn't mind, but because of something bigger it just bothers.
I should get better at letting things go, at accepting the past and concentrate in the present and future, hut it's just so hard...
