Hang it just as it is and enjoy looking at it every day. Your subconscious mind will work on it and when you are ready and have your mojo back, you'll likely be surprised at how easily the new work progresses.
That said I can so relate to your 'malaise' and the stress you are under. It's a kind of depression and even grief process. Like other forms of grief, it needs time to work through. Sometimes a little temporary chemical help provides relief. If you opt not to go that route, it's okay, and we all support you. But stay with us so that if this lingers we can all listen, send cyber hugs and encouragement, and help make sure you don't get stuck for the long term.
Your project really is terrific and will stay that way while you enjoy it this way!
