Could numbness and weakness in arms be related to anxiety

I had really bad anxiety for years. Medication caused more anxiety. I would get it while driving and was scared to even get in the car. One day I was fed up with it and fought it, because I knew it wasn't going to hurt me.  I wasn't going to let it take over my life.  My decision was after reading about how it keeps people in there houses and I could see this happening. I talked my way out of many episodes and they eventually slowly went away. Yes, you can control it with your mind. Your mind can do wonderful things. Good Luck!

ps....many anxiety medications cause anxiety 

I suffered with anxiety a few years ago, I used to work in a call centre and on top of that my diet was really bad and had a low immune system and was stressed with my driving test and everything, it all mounted up and I started feeling dizzy one day at work, which eventually turned into panic attacks and I got really bad numbness in my head, legs, stomach, back etc and bad headaches, heartburn, derealisation, depersonalisation. I still have the numbness now and occasional headaches but no panic attacks. I went on the Linden method website, a guy named Charles Linden from the UK who suffered with anxiety since he was young and cured himself made something called the Linden method, it helped me a bit but you have to do the leg work to help yourself get better. Plus I turned to my religion and prayed a lot so eventually the panic attacks went away. I also used to get acupuncture done and took herbal medication, which helped get rid of some of the symptoms. Counselling doesn't help, it makes you think about the anxiety even more, it's better to talk to people who really care about you like your family. Basically, you need to improve your diet, light exercise, keep doing your normal everyday things but also you need to find something fun to do to keep you occupied throughout the day like painting, drawing, photography, baking cakes etc and nothing too stressful and you'll get there, the panic attacks will eventually go. Just remember, the panic attacks won't kill you, don't let them take over your life.
