What did they mean 'in your head" like you don't really have anxiety? Holy cow. At any rate there are some things you can take like valerian, st johns wart but the best thing for you to do is try to determine what stressors are causing your anxiety and why. Are you anxious about the anxiety (do you worry about it at home after the fact?) Is it happening more and more and with less and less triggers? If you find yourself reliving the anxiety at home after you had the anxiety then you must stop doing that because that is why they are getting worse. Don't allow yourself to rethink it. If anxiety happens, the minute it's gone let it go and don't even think about it. Go on about your day. It's in the past. It happened. It's done. Yes you might have another one in 10 minutes or...you might not. If you do, the minute it's gone, don't think about it. In this way you are reprogramming your brain away from the anxiety instead of building a rut in y our brain to continue to have anxiety. I have to say, this technique took me ten years to virtually eliminate some very, very severe anxiety but it started to work right away. Meaning, right away I had a little fewer incidents. then a bit fewer and farther between to where they were months apart. (This is why I have to say it takes years because sometimes after months of freedom I'd have anxiety AGAIN but I had the skill to deal with it and eventuallyl it went away altogether). Another anxiety stressor is alcohol. Drinking alcohol exacerbates anxiety the next day.

I agree with DoSomething about figuring out what it is causing your anxiety and trying to deal with it.

However, having been in that situation where even if you know why you are upset you can't seem to push it away, I would recommend Benadryl OTC. Just a normal dose, 1 or 2 pills, it tends to relax most people and is an antihistamine which is a common type of medicine used to treat nausea, anxiety, insomnia, all sorts of things besides just a runny nose. If you have taken Benadryl for something else in that past and it has hyped you up though (it does that to a few people but it's fairly rare) then don't use it for anxiety. Also, don't use it around the clock because it will dry your sinuses out and give you a headache if you use it too often. I hope this helps.
