Ignoring yourself is a desperate cry for help. I suspect that you saw a provider who wasn't really into you. Your subconscious mind, unable to process this attack to your self esteem, manifested itself in this destructive behavior. Her indifference is causing you to question your own self worth, driving you to ignore your very existence. Perhaps with the right therapist and years of counseling, you may, one day, be able to hobby again.  This is known as Totally Bored Provider Syndrome or Total BS for short.
