Your life is EXACTLY like mine was a few months ago! My son turns 2 in November and I just weaned him a week ago. It has taken me pretty much a year, to cut down his feeds gradually to get to this point. First of all, with the day, I cut out all daytime feeds immediately. This was easy enough to do by keeping very busy during the day and going out a lot until he forgot about it. Then I was down to one feed after the bath, SEVERAL during the night and another in the morning. With the night ones, I went cold turkey. He sleeps with me so it was hard but everytime he woke screaming for a feed I would repeat "nighttime is for sleeping". After about 2-3 nights of tantrums he accepted it. I did not feel too bad because he at least was in bed with me and could have cuddles, just not feeds. Our nights got a LOT better after this, to the point now that he usually wakes once during the night (to leave his cot for my bed) and then not again until morning. I felt like a new woman. Good luck.
