Final of episode of lost until next year? I'm rather confuzzled?

Hey i watched the final episode of lost till next year (in england) and i'm well confused, we kept getting clips of Jack, with his rather bushy beard, and he met Kate and said we were meant to leave, i mean dus this mean it's clips of the future, but the reason i think not is because wen he's in the hospital, he says go upstairs and if im more drunk than my father, u can fire me, yet his fathers long dead if it's the future, either that or he's off his head completely wen he sed it cos of those drugs, please to dumb comments, i want a good answer, and whoever unveils the most, gets 10 points!

These are called Flash Forwards. Jack is finding it hard to adjust to life of the island and is addicted to a drug called oxcodone. The funeral he goes to could be John Lockes, Bens or Jacobs, most possibly Locke as he has no family, the book with the name of the deceased begins with J and Jack says he should've listened to him (not called the boat) .The Funeral parlor Hoffs/Drawlar is an anagram for Flash Forward. When he saves the woman from the car the doctor says that he is still saving lives (referring to the island). He flies on the planes so much because he wants it to happen again (for the plane to crash back into the island). He meets Kate who says she has to get back to him (maybe Sawyer?). Jack says they have to go back referring to the island. With Jacks dad, either he's off his head reffering to something else or it could be a parrallel future flash forward type of thing.
