My experience as a reader for others and for myself (for 11 years) is that if they are allowed to dominate, strong emotions of all kinds affect both the reader and the querent, and do indeed attract cards that reflect those emotions rather than answering the question at hand. If uppermost in your mind while you are shuffling and drawing is fear (or anger, or desire), then cards mirroring that fear will come up in the reading, for that is where your focus is concentrated. That is the reason why it's important for the reader to ground, centre and detach before and during a reading, by whatever means suits that reader. (Likewise, if you are reading for others, it's good if you have your querents shuffle and when you notice they are agitated or emotional, find ways of calming and grounding them.)
Some readers detach naturally, others - particularly when reading for themselves or those close to them - have to make an effort to ground and centre (I'm in the latter category).
Once you are detached and able to focus clearly on a question, then the cards you draw are those that answer the question. They will also relate to the emotional background of that question, but not in such a direct, dominant way.
In your case, ask yourself what your state of mind was when you drew these cards you are afraid of. Make an effort to ground and centre before you read - take your time shuffling and focussing on the question, and do whatever helps you to detach from your emotions, including the fear of drawing certain cards (if you search this forum, there are many ways suggested, from use of incense, crystals and prayers to breathing and visualisation exercises, to simple routine ways of setting up your reading space and shuffling).
Something else you might want to do is to take all the cards you fear out of the pack, and start journalling them. Journalling is a great study aid, but also helps in achieving detachment. Have a dialogue with those cards, explore them in the round - their negative and positive sides. Examine why you fear them. In no time you will find that the fear recedes. Doing a card-a-day draw and journalling it also helps. Whenever a card you are uncomfortable with appears, you can examine it in the light of your day. Look at it morning and evening, and ask yourself - how has that energy affected me today? Was this fear justified?
Yet another way of overcoming that fear is to read for others. If you don't feel ready for that, read for fictional characters, tv characters or personalities, the news, your pets, etc. Practice reading for others as much as possible. Centre yourself and focus before drawing the cards, and read them as straight as you can.
Good luck!
