Hypnotherapy isn't going to help
and I can't see that your anxiety is likely to be caused directly by those particular experiences - more likely to what happened as a consequence.
the thing is - you can get addicted to therapy - It's great isn't it - for whatever time you are the centre of attention.
cbt as you say is less intimate but it's still it's very personal.
It's normal that as you find your way round the "system" you'll see "faults" and alternatives
there are many approaches ...
but cbt is about learning to cope . not healing - just coping with the effects of whatever hits you
The psychriatrist "breakthrough" is very different
If you've been assessed and cbt is thought to be in your best interests ... give it some time ...
stopping smoking takes 3 days to break the addiction, 3 weeks to break the habit.
but people still fancy a fag after a meal or with a drink - sometimes for the rest of their lives - the cbt here, wanting but not needing takes longer.... but gives you the ability to control the situation
