I'd echo what Mariah said about meditation. Mindfulness has now replaced alcohol as my "quick fix" solution for anxiety. As soon as I feel my anxiety levels rising, I find somewhere quiet and focus on my breathing. Sounds far too simple to work but it's a lot more effective than drinking a load of poison. My mind darts all over the place and I find the lengthy meditations difficult so I listen to 10 minute meditations that I find on youtube. I try to do 10 minutes every morning and I can tell the days I haven't done it as anxiety seems to creep up on me quicker.
If you haven't tried mindfulness yet, I'd definitely give it a go. It certainly won't do you any harm. Good luck
