Feels like I have a constant electric feeling going through me especially at night... HELP!!

Hi everyone I have been having extreme anxiety/panic attacks since a few weeks ago. Its progressively gotten so bad that my body constantly feels like it has a rush of adrenaline in it even when I am remaining relaxed. During the day I can kinda manage it as of right now but sometimes still need half a xanax. At night its progressively gotten worse to where I wake up pretty much every hour with worse adrenaline feeling as in extremely shakey, sweaty, heart racing etc. i cannot control this and even when i go to sleep relaxed my body just goes into this mode. As I am falling asleep it jolts me back up in the beginning too until I am so tired that it instead wakes me up every hour or two with these extreme symptoms. This happens even when I take a xanax. I have only take two xanax so far in the span of a week(0.25mg) dose but this is the only thing that has given me relief. I just want it to end and if all this adrenaline would stop coursing through me id probs be okay. Its hell every night now and I cannot even sleep whereas before id maybe wake up once or twice and still sleep for 7/8 hours but its just gotten worse this past week. Idk how to help myself and I am so scared. Im not on any other meds yet. I was trialing celexa but had to stop after a few days due to symptoms so waiting for my GP to discuss this. I only have the xanax to help currently. I am so desperate please any advice or help. :(
