I go to a therapist just so I can lie to her I made up an entire fake life story full of fake problems and she wastes her time helping me with them
Does your therapist believe your lies? Do you not want her help then?
Yes it is because psychiatrists and mental health professionals in general can't actually be your friends and it's just a waste of money
It is okay to be doubtful about people not being able to help but wasting a therapist time is not good. They could be helping somebody who actually wants help.
I've got nothing else to do with my time.
Your only wasting your own time, money and energy. Surely there is something more productive that you should be doing. Find an interest and pursue it, hang out with your friends or family, or go exercising, literally anything else would make you feel more accomplished.
