Over the years I’ve tried talking therapies, of various sorts, on a number of occasions and each time I have found they don’t work even if one persists with them for a protracted period.
In fact it is my contention that they don’t really work for anyone, although some may be able to delude themselves and reach a cosmetic resolution — which I guess is working of a sort.

Last evening I was reading a blog post by our favourite zen master, Brad Warner under the banner I Hate Myself. Brad points out that the root of the problem is that the “I” and the “Self” are one and the same, so trying to fix one to fix the other is as useful as trying to argue your way out of a paper bag — pointless and productive of very little. And because we become aware of our failure it often makes the situation worse, rather than better.
Indeed it seems to me this is what talking therapies are trying to do: to fix (your variant of) “I Hate Myself” by getting you to separate the “I” and the “Self” when this is neither possible nor sensible.
And this is why talking therapies don’t generally work: they’re based on the false premise that “I” and “Self” are different and can be separated.
