Meditation can be beneficial, but ( from my own experience) it takes time, practice and patience. When i was at the pinnacle of my panic attacks/anxiety i went to this pseudo-psychologist guy that helped me "master" meditation, i could see some benefits right away (less/not as aggressive panic attacks) but i just lost patience and decided not to continue with meditation (a decision i regret).
Just be careful about online medication websites, lots of scammers out there. I would recommend to go to forums instead of websites that offers help. There is a lot of resources here - http://www.dreamviews.com/forum.php (i know is mainly about Lucid Dreaming but there is ton of stuff on meditation as well)
I will also recommend you to listen to Sam Harris talk about meditation, he is a bit if an aggressive cunt most of the time, but somehow listening to him talk about meditation gives a lot of skeptics belief in meditation.
