My mind getting too toxic...

My family set virtually no expectations to me but I just can't forgive myself for being mediocre. I realized I'm not a genius. I'm not earning millions, not getting into Ivies, not influential or popular, and not even having specializations. I hate my mind but sometimes I can't help with it. Any advices? I can't take it no more. I hate myself and I hate me hating myself which is paradoxical.
