You have to start with yourself; if you have no "fuel" from inside, you can't connect outside, it is like trying to drive a car in traffic with no gas.
You can't be good at anything if you don't do anything; all things worth being good at take time and effort and interest in something doesn't just appear automatically. Right now you are interested in making the big empty hole go away; I would find a therapist or go to the library and load up on books, see if I can't do a "Self" project to find out what might interest me and be worth pursuing.
Did you see the movie "Runaway Bride?" I love the part in there where Richard Gere points out to Julia Roberts that she doesn't even know what kind of eggs she likes for breakfast and, later in the movie, you see Julia with a huge table covered with eggs cooked 10 ways, trying each one so she will know her own preferences. You have to do that do know what you are interested in, you have to seriously look!
I found this book very helpful:
