First of all, from what I can see, your quilt is beautiful. Second of all, you CAN do this. You need to roll your quilt so the middle row is under the needle. Begin there, and work your way out to the edge. Flip the quilt around and do the other half. Just take your time and walk away for a bit if you need to, but don't give up. I have quilted up to a queen on my domestic machine. I've also found that spray basting works a whole lot better than pinning. You might want to give it a try. Good luck and don't get discouraged. We are all rooting for ya.
