Not infrequently those who have benefited from LP suggest that those who have not benefited or do not undertake LP are negative, defeatist etc. This is cruel and hurtful to many ME sufferers and importantly does not stand up to examination, even in the world of ME/CFS "headologies".
LP is reliant on testimonies from its beneficiaries. There are numerous therapies on the market for ME/CFS sufferers, similarly reliant on testimonies. If negativity were the issue, those who claim no benefit from LP would not go on to claim benefit from Gupta, Rowan Bodymind, MT, RT etc., yet some do (and vice versa). I am not advocating or criticizing any of these here, but motivation is unlikely to have been the issue or they would have failed at all such therapies.
LP, Rowan and Gupta share many similarities but since some patients have/claim success with one and not the other, appropriateness of the therapy was probably the central issue. These therapies differ somewhat in concept (not perhaps greatly). They have some differences in delivery/practice and presentation seems to be important to individual outcomes - all according to the type testimonials/reviews on which LP relies. However that may be, "I did well on therapy X, but not on LP" is not the testimony of a demotivated, negative, defeatist person. Thus, even in the world of ME "headologies", LP insinuations/accusations of defeatism etc. do not stack up.
Of course, since belief/commitment to LP is part of the cure, this may rarely if ever be admitted by individuals who have benefited, but they could testify, if they wish, without attacking others.
All insinuations of negativity if you don't do well at LP or do not do it should be condemned and discouraged immediately by LP and particularly by any NHS associated practitioners/researchers.
For my part I believe LP etc may help some with a diagnosis of ME and am glad for them but ME/CFS is not as yet properly sub-grouped and none of these therapies should claim to treat ME per se or promote accusation of failures/refuseniks.
The broad issue of demotivation as a problem among the chronically ill is a legitimate area of concern: the equation "support/do LP or you are demotivated/negative etc." is an entirely illegitimate accretion.
