Boredom, hope, reassurance, self esteem boost, habit, addiction?  
I'm hoping to have a relationship where I will have NO need to call psychic.  That's my wish.  If I need to call a psychic because of a man and having to find out his feelings, thoughts, intentions etc, then that man doesn't deserve me!  That's what I'm working towards. 
I notice when I don't call for a while and focus on my life, I do much better.  Then, I call, really for no specific reason or a need to, kind of just to check in and then I start all over again, worrying, stressing, obsession which leads to more calling.  I seriously am SOOOOO much better when I DON'T call and just trust God, the universe and my own instinct.
