Greetings...Well... The Tarot is a tool that can give us access to vast amounts of information. Basically Life is one gigantic mass of information.
Some of it we like, and others of it we do not like. We like weddings and promotions, unexpected windfalls of money and new children on the way... we do not care for spending money to fix the house or the car, taking care of our medical issues or surgeries, and we tend as a rule, not to like the subjects of divorce, separation, loss and death.
However we may dislike them, they are a part of Life... and if you are dealing with the Tarot, you are dealing with Life in all its manifestations and permutations.
My suggestion is to understand that fact and then decide.. do you want to access that information or not? Accessing it brings with it certain responsibilities (another thing we as humans tend not to love) to the person for whom we are reading.
Sometimes the best we can do is to gently warn someone of a difficult time ahead, and perhaps offer suggestions that might help them to avoid or ameliorate the issues that we see.
I suppose it really depends on the use to which you wish to put your cards. Do you want to read for others or yourself? Or would you rather use them as a tool for meditation and contemplation? Perhaps you might wish to use them in working magic?
My advice.. if you fear them... leave them to the side and find something with which you are more comfortable. Or work with them for a while and see how you feel about them.
In as gentle a way as I can manage to say it... you can get over your fear by facing it down. Or perhaps you will decide just to avoid it. My belief is that there is nothing to fear...
What is yours?
Blessed Be...

P.S. The whole point of any of the mantic (predictive) arts is to better understand ourselves, others and the world around us. As the admonition carved over the entrance to the Temple of the Oracle at Delphi said: Know Thyself. My question then, is what is there about yourself you would wish not to know? Remember... The Soul always has Free Will Choice. As they say, forewarned is forearmed!
