You are trying to suppress thinking, which is pointless. What happens if you try not to think of a pink elephant? Huh? Keep trying your hardest NOT to think of a pink elephant…go on…

You see, suppressing thinking isn’t really an answer. Read up and do some mindfulness meditation, this is about letting thoughts come and go without judging them and observing them from a distance. If you are suppressing the thinking you are trying to avoid feeling a certain way, but what you need to do is to observe the thoughts from a distance and feel whatever comes up. If it gets too overwhelming you can return to the sensations of breathing in and out. So start doing mindfulness meditation which I highly recommend for you.

Also, read the book “You Can Be Happy No Matter What” by Richard Carlson. If you read that you’ll realize what’s happening with you and you’ll understand why you don’t need to suppress your thoughts.

Good luck
All best.
