I won't call it a disorder necessarily but obviously it's not normal either. I do have seeking validation from outside problem, and I have worked on it through this sublimnal video -

Though I know you are not talking about seeking validation in day to day life, you are talking about nonstop calls to psychic for validation. For me, I realized it's the
fear of unknown and fear of future - what if nothing changes, what if I am left behind and everyone moves forward in life, family, career.. and what if I never get over this.. and calling psychics and listening about the future love that may come into our live or return of POI gives us hope and soothes the anxiety for sometime.
Try to identify your triggers and see if you can work with them.
Also - I am trying to look at it as a life lesson. I can't bring back the money, time or my POI. But I am thinking maybe there is a life lesson here and some healing I need to do, beliefs I need to clear and if I don't do it now maybe I will put myself in same pattern again some other time.
