First off, from what I can see your quilt is very pretty. Beautiful choice of colors. As a new newbie, I had the same issue. I use the term new newbie because I feel like I'm still learning all kinds of stuff 3 years later.
Now, to your question, several people have already mentioned rolling it. That's the way to go. Take your time, work in small sections on your quilt. Continue to breathe. It will take some time but you'll get through it. I did. For the record, it may seem daunting but, it will be rewarding when you're done.
