@bob_some_ale my understanding is that in order to resolve most phobia issues you are eventually going to go through some type of exposure therapy. In this case start with a very small descent and work up to larger and larger ones. If you think you can push yourself to do it on your own give it a try. Otherwise you may need someone to help keep you motivated or work through whatever the underlying issue is. Standard disclaimer that I am not a therapist and if you think you might benefit from professional help then you should pursue that. Just because there is a profit motive behind it, doesn’t mean it doesn’t work or can’t be helpful.
