I've been suffering from real thought-broadcasting for a long time...
Do you have any idea how to cure it?
Yes. Here's something which I think could work if you're willing to try it.
First, find someone you trust and ask for them if they will help you conduct an experiment.
Here's the experiment.
(1.) Get a well-shuffled deck of cards. Sit across the table from your friend and select a card from the deck (making sure your friend doesn't see which card you have selected). Don't say anything to your friend (as this might inadvertently reveal which card you selected) but think about what card it is. Your friend's task is to receive your thoughts and write down what the card is. After your friend has written down what card your thought transmissions told them you selected, show them what the card is and record whether the card they picked up from your thoughts is the one you actually selected.
Repeat this test 5 times. Now look at your records. How many times did your friend accurately receive your thoughts?
(2) Same basic set-up: you and your friend sit across from each other. For this test, you write down a number from 1 to 100 on a pad of paper, being careful not to let your friend see what number you are writing while you are writing it or after you have written it. Again, don't say anything to your friend but think about what number it is. Your friend's task is to receive your thoughts and write down what number your thought transmissions tell them you chose. After they have written down what your thought transmissions told them, show them what number you wrote down and record whether the number they picked up from your thoughts is the one you actually selected.
Repeat this test 5 times. Now look at your records. How many times did your friend accurately receive your thoughts?
(3) If your friend accurately identified the card you picked most times you conducted the test, and accurately identified the number you chose most times you conducted the test, then contact a skeptics' group and request to perform this test in front of them. If your friend really was able to accurately identify the cards and the numbers you selected, with no cheating or fakery going on, then you appear to have a genuine paranormal ability and are in line to win $1,000,000 from the James Randi Educational Foundation.
(4) If your friend did not accurately identify the cards and numbers you picked most of the times you conducted the test, then it appears you do not have a genuine paranormal ability and your feeling that you are transmitting your thoughts to others is mistaken. You need to find out why you think you are transmitting your thoughts when evidently you are not. Talk with your friends and family and see if they can suggest someone who might be able to help you figure this out.
