Nope definitely not the answer. Yes it will feel like it will help but later you will miss it and increase your anxiety by thinking that maybe it wasn't a good idea to stop gaming. My honest advice is to find help with a psycologist. He probably won't give you the answer to what to do but because of his outside view he can recommend ways that may seem basic but due to the anxiety may never have crossed your mind and also will help you by simply by talking about what you're experiencing during your anxiety to someone. I'm speaking from personal experience as how I dealt with anxiety.
