Hi Marisa
I would say that if something sounds too good to be true, then it generally isn't true.
There are tons of methods you can use as an anchor to alleviate anxiety. There have been many fashionable ones (snapping elastic bands, tapping and so on).
It's basic CBT and I would hazard a good guess that you can find similar techniques on You Tube for free.
That said, if you are prepared to spend hard earned cash, I would opt for a therapist (one that someone can recommend to you and has had success with).
Whilst anxiety presents similar physical symptoms in people, the resulting behaviours, thoughts and histories differ and vary immensely. (What works for one doesn't work for someone else).
As for "one cure fits all" there simply isn't one.
