I dont have a companion with me and everytime I try to get one they says "looks you already have someone with you"
I tried waiting a week and nothing happend its the same problem.

do you have a console command I should do to fix that problem or anything?

Try typing "help Lydia 4" into the console, then "player.placeatme [the code that comes up from the help lydia 4]" then tell her its time to part ways, then you can r enter the console and click on her and type "disable", if you wish.
