.5 xanax safe everyday? Who takes Xanax everyday for panic / anxiety?

I recently was very sick and now have anxiety from it. I find I’m having to take .5 of Xanax everyday. Usually only in the morning. I wake up panicking or having anxiety. How long has anyone been taking Xanax? It’s the only thing that works for me right now. I’ve been taking it a couple weeks now.
