You were drinking...how terrible....
Looking back on my life, if I had been caught for all the things I may have done, I would still be in jail. If I had got hurt every time I had made a decision that could of ended in disaster I would still be in a wheel chair.
You are lucky not to be worse hurt, and strangely enough you probably have the drink to thank for that, people who are drunk and relaxed often survive things better
Wishing you a speedy recovery, for now while you are badly hurt, stay ahead of the pain, take those pills on time, if you start hurting you are getting behind and it is difficult to catch up.
OH, and start moving the bits that do move as soon as you can, so very important to get going as soon as the medics say it's OK, even if it is just making a fist and relaxing, or wiggling your toes, whatever moves, keep it moving.
