Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread. General anxiety caused by routine day-to-day stresses usually passes quickly and is experienced by almost everyone at one time or another. However, such feelings that linger over time and are very difficult to cope with, and which lack a clear cause, may indicate...

The fear of the fear itself is the hardest part to just push through, once you do that, the levels even out naturally.
The problem with anxiety is that it's a cycle. You have a horrible attack and then you become afraid of having another attack which fuels your next attack. Now, before you start worrying about worrying, remember that you have control. You have a lot of power over this.
When you feel anxiety coming on, try doing things that make you happy - that make you feel warm and fuzzy inside. Don't let your mind fixate on negative thoughts about injury, death, sickness, anxiety, etc. If you notice yourself obsessing, find something to distract yourself with. I watch funny movies or do crossword puzzles or call my friends.
I know it's easier said than done, but if you keep up with it it really will help. I still have mild anxiety problems now and again, but I haven't had a panic attack in over 8 years. I remind myself that it's just anxiety and nothing bad is going to happen.
Good luck and I hope this helped a little!
About 30% of people have the MTHFR gene mutation which makes it difficult for them to convert folic acid into folate. Folate is a B vitamin critical to neurological function and people with the gene mutation tend to have super low folate levels. They can also have low B12 levels which can wreck havoc neurologically. A doctor can do a blood test for your folate and B12 levels as well as for the MTHFR gene mutation.
If you have the mutation, you just take a special sort of folate (and/or B12).
I found out I had the mutation a year ago and after 40 years of anxiety attacks, I started on the methylized folate and haven't had an anxiety attack since.
If that's not the issue, propranalol might help. It regulates heart rate so that the chain of anxiety is broken before it can start. It can also help resolve anxiety attacks.
If you just can't stand the feeling of anxiety, xanex, klonopin or ativan can be used but they are tranquilizers so you might wind up falling asleep.
Beyond pharmaceuticals, meditation helps, a soothing bath, a cup of tea, calling a friend. And there are crisis lines you can call as well.
That being said, a lot of people will have one or two anxiety attacks in their whole lifetime and that's it. It's a very common issue and there are tons of solutions.
