Yes, CBT could help you to identify how irrational your thoughts are, so you could seeing they are not factual/irrational. I have used CBT and it works. Sometimes, I encounter emotions and must identify the responsible thoughts first and this takes some degree of awareness. I also do not fight with my thoughts. Emotional reactions to thoughts and thoughts about them seem to make them stronger. I get calm and observe the thought from a non-judgmental perspective, kind of like a spectator, without emotion. The thought is allowed to pass and recognizing it is irrational is also helpful. Your thoughts only hurt you if you give them that weight.

Meds could also help reduce the anxiety associated with your fears and make it easier.

As far as "knowing" God does not love you, if He exists, Christianity teaches God's love and forgiveness is unconditional. You are spiritual, so start there and seek what beliefs fit you best, if you are so inclined to seek a religion, faith or a form of spirituality.
