Tanya, I've "pulled" a few training articles from PezCyclingNews.com that you might find helpful. As the first article suggests, how to approach your training depends, in part, on what kind of climbing you're struggling with, i.e., short, steep climbs or longer, sustained climbs. There's also a bit of an explanation on what's meant by your power to weight ratio.

Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
