Hello & welcome to the DhO,
Nika Japaridze:
Do any of you have advice or experience on how to "look at my beliefs... to stop the automatic reaction of denying and repressing the emotion"?
Here is a good place to start: http://www.actualfreedom.com.au/richard/articles/thismomentofbeingalive.htm
After having read that, dig around the site looking for terms mentioned in that passage (so that you may then understand more clearly the words expressed on that page and thus the method itself); those terms such as: naivete, apperception, etc.
There are many specific examples of investigating the nitty-gritty behind beliefs in the sections written by Vineeto and Peter. One such page that 'I' found quite useful: http://www.actualfreedom.com.au/actualism/vineeto/selected-correspondence/corr-love.htm
If the method is then still unclear-- having read through all of that and the related passages-- please post again.
