A thought about psyche: If you are not used to spending time alone during your daily life, backpacking alone can really amplify the "aloneness". However, I take it from your post that you are planning your trip as a dayhike? I find that day hiking alone can be refreshing, but in unfamiliar territory, I also find it can be stressful.
I would make every effort to find a buddy, but if you do not, I would not let it stop you, either.
