and Mandi, for sure, your smallness is an asset. TRUST US on that.
It took me 3 years to build strength enough to ride anywhere, and that does NOT include steep hills. Someone just bragged that they have only walked 3 times.... I can't tell you how many times I have walked up hills. HOWEVER, I have gotten stronger (and darn, as I've gotten stronger, I've gotten heavier, I must have gained 10 lbs just in my legs, and it shows)
and I have actually done an 18 mile hillclimb and some other rides that were JUST all about hills. (and I still walk sometimes)

So I can promise you, if you keep working at it you will get better.

ps, can you put your bike in your car and start somewhere a little better? I don't envy your hills!
