Whoa thats kinda harsh lol, probably just another way to make money at the expense of people but i cant say much really as i've never tried them. Ive kind of always thought they were useless in improving your condition and there more just make you shutup about it. I mean i honestly think the only way people will get over stuff like this is by either learning to cope with the conflict or whatever in your head or defeating it altogether. That seems like the only cure, to actually change your thoughts rather than stopping you from thinking. As thats exactly how a placebo works, you think your going to get better so you actually do as you have some positivity, it just kinda shows its all in your head sometimes.
But yeah i've never used them and never really really needed to so im gonna be biased.
