If you don't love or hate yourself and enjoy life and your psychologist agrees that you are not depressed chances are you're not depressed. As far as what is wrong with you, it's hard to say. You may just be going through a phase. You should continue seeing your psychologist to ensure that these feelings don't get worse.
