I have the same issue with my parents. Made it worst when I had my drinking problem. Would be good to have a good talk with your mom. Would be also good to move out if you have the money and tell her that you will mail her a check each month until you pay her back. For her to take your paycheck is illegal and bad judgement because you will have a harder time living on your own and learning responsible. I know for first hand with that and I'm 29 years old.
Talk, talk and talk about this to her and if you can move out.
Not trying to tell you what to do but a lot of kids have trouble living on their own with controlling parents.
