I have anxiety, but just occasionally now. I no longer "suffer" from it. I used to have it much more often and did suffer from it. And yes, Valium and Klonopin do help a great deal. There are other meds and supplements which can help, as well. I'm careful with the anxiety meds and don't take them any more often than needed, which is only when I feel out of control with my anxiety.
Now, when I notice anxiety, I don't let it overtake me. I use it as an indicator which leads me to why I'm anxious - what belief(s) might underlie it. I know my anxiety is an indication of some kind of conflict between some (acquired) belief and my (natural, inherent) Inner Being, which contains NO anxiety. When I can let go of my resistance to whatever beliefs are behind my anxiety and have the willingness to explore what's resulting in the discord between me and ME, it helps me to see the mechanics of that discord. It reminds me that whatever I'm anxious about isn't happening in the present moment - that it's coming from some unresolved, past experience which has me scared about the present or the future.
To someone having an anxiety attack, I know this process would be more in the way than of the way. It may just lead to more anxiety, in which case an anxiety med might be an appropriate intervention as a crutch until there's more resolve as to why the anxiety is happening.
When your anxiety is really severe, I think the effect of an anxiety med highly outweighs any side effects of it. That's what's been true in my case.
