January is not any sheep's natural time to lamb on the west coast of Scotland, but you don't say what breed the ewes/tup are.
And yes, we have ALL been there and will be again. You will be able to get through this horrible lambing season, and once you are through, sit down and write it all up - what went badly, what went well, what did you manage to save despite the odds being against it, what was the worst of it. Then leave it in a drawer for a few weeks, go back to it and plan for next year. It will be better - because you will make changes! You might reduce the number of ewes, change the layout of your field so tup is further away, get a different breed of sheep etc etc.
I personally wouldn't recommend the whisky at 3am though, but that's just me. Chocolate is much more my thing... or taking the dog out for a walk (even at 3am).
