HELP WIH MY FRIEND? SHOULD I BREAK IT oFF?

Okay so me and my friend had a rough friendship. It was awful we fought all the time and everything. We are 100% oppisite. She leaves me out alot and she has AlOT of drama and makes sure I know it. She can be a jerk and takes things the worng way and things are going downhill right now and I thought we were maing progress. She can be mean or nice and I am tired of being pushed around by her. If I tlk to her she takes it the wrong way. The problem is I dont want to get rid of her cuz she lives at a campground and she is my ONLY friend at the campground. So if I leave I will be friendless adn I do not make friends easy. What do I do? If I break it off how do I do so?? *cry*
