I can tell you about what most of the research says about treatment, but with a word about newer things that have very encouraging research.

The National Institute for Clinical Excellence, an official British health agency, has statistics on what's best for most patients. That's most - not you as an individual. They rank 3 treatments - 1) therapy (cognitive-behavioral therapy - CBT), 2) medicine (generally antidepressant), 3) self-help based on CBT.

In recent years, there's been very encouraging evidence about traditional practices, especially controlled breathing.

Of all the traditional mind-body practices (meditation, etc.), the one with the best evidence for affecting mood disorders is yoga breathing. Slow breathing is used for treating anxiety, depression, panic disorder, and PTSD. It's safe and it doesn't take any training. You can find out about the work of psychiatrists Richard Brown and Patricia Gerbarg and PTSD therapist Emma Seppala in answers like this one.

It's safe to say that these methods can serve as complementary treatments - things that enhance effects of the standard treatments.

Yes, that's almost textbook anxiety, and the only help you're likely to get is if you stand up, find yourself a therapist or counselor and GO SPEAK WITH THEM.
