Can I be honest here? I want to cut ties with my close friend of 4 years because I don't want to deal with his drama anymore.
Drama is everywhere, why would his be any different? Why don't you want to deal with his drama?
He's too dramatic for me, always thinking about things which are not in his control.
It's fine if you want to end a friendship. You shouldn't be friends with people you don't like.
That is not a reason at all. I'm done with him because I don't want to be involved with his uncontrolled drama.
Okay okay, you have your reasons and they are valid. Stop seeing this friend at least for awhile and maybe things will improve about your mood too.
