Progress deleted, character deleted, all in game items such as skins deleted

I logged into my game this morning to find that not only had my main character dropped the 4 levels I had gained the day before, my other character had been deleted. When i entered the game I was farther back in the story, recieving tutorial updates all over again (like how to open map or use skill points) and all of my character mods like skins and heads that I had earned throughout the game were also gone. Everything was working fine when I exited the game the night before. I don’t know what to do to fix this.
