Once I was in a situation,where I could not be an unpaid slave anymore because I was physically and emotionally exhausted.I was treated very bad and taken on guilttrips.They acted as if I do not exist.I could not take the psychological torture and asked what was my fault.They said I was not being useful to them anymore,so I am disposable.So I had to decide whether become a physical and emotional slave to them or take the abuse.I stopped the slavery.You can guess what I got in exchange?????? Silent treatment,sarcasm, abuse,emotional guilt trips.and so on.
