Well.... a competent therapist can be very helpful. But I notice you live in the UK . (“Good” therapists do exist in the uk but can be hard to locate........ )

I think Skeezyks links are helpful .. good luck

Posting online helps some people with this disorder. If the self loathing is severe I suggest caution ... as everywhere else, there are some who feed on those who may be “vulnerable” . But pc is a “safe” forum.
