My boss was this way to me, called me every name in the book. she violated so many labor laws. but i needed a job and it was good money, but every day beatting me down with her words. and it worked, she basically took all my self esteem away from me. it's been 5 years and i have finally become the assertive person i used to be before her.
No one is stupid and your not stupid. i wish words wouldn't hurt so much. misery loves company, take pity for people like that they must live such a lonely miserable life.
