Those withdrawals sound terrible! I have gone through them a few times, and each time they get worse. On a positive note, congratulations on the decision to achieve sobriety at such a young age. You have a whole life ahead of you that you will discover is so much more rewarding sober. It seems hard to comprehend right now, but in the end you will see it. Welcome here, as you will fund much support around here!
As for your detoxing, I would contact a medical professional. There will be many people around soon telling you the same thing. I didn't and at times wish I would have. However, I wasn't drinking as much as you. We are not allowed to give medical advice on here, so your best bet would be to contact someone for help.
I hope you get through this, and stay strong. We have all been where you are and have found a better way of life. You will too!
