Can Xanex help with caffeine withdrawal symptoms?

I was an excessive caffeine person (5 cups of iced tea, 2 cups of coffee and chocolate daily for 5 years). I stopped cold turkey and have had inner tremors, with daily headaches, rapid heart rate and dizzy. I had a panic attack the day before I cut out all caffeine (because I thought that was the cause). I had blood work, an ECHO, chest xray, EKG...all normal and was told it was anxiety and was given xanex. Most of the time I am not even thinking about anything when my heart starts racing and I get jittery. It is either me being afraid of having another panic attack or caffeine withdrawal...I don't think I would develop a panic disorder over night. But the Xanex does help me when I get those jittery, dizzy symptoms (I only need one .25mg when needed). Is it possible that Xanex could reduce the symptoms of caffeine withdrawal????????? The other symptoms I have that I don't think is common with caffeine withdrawal is...red spots in eyes especially when looking at computer screen that follows my eyes as I move them (noticed just today), white spots (floaters), semi blurred vision that I have never had before, lightheaded, heart beats really funny right when i open my eyes in the morning, heat intolerance (that I never had before my panic attack a month ago), heart skips beats, lower back pain, acid reflux, I have PCOS and hidratenitis superrateva (HS), I have had a low grade fever in the last month which I never get fevers, spotting when my period is not even close, sharp pain for belly button down, constant lower abdominal fullness, sharp pains under my left breast (like under my rib) sometimes...I just want to be normal again! I am a 27 year old female with a 2 year old son...I was normal a month ago and now I am not and I am frustrated!!!!! Please any thoughts!???!?!?! The PCOS, HS, acid reflux, spotting and sharp pain from belly button down are the only things that i have had prior to the panic attack. Everything else appeared the day after the attack which was the same day i cut out all caffeine.
