So, JoeLena, keep sailing your R19. The only thing you have to worry about is when the wind is strong enough your R19 can get knocked down. For strong wind you can either put a reef in the main sail or drop the jib and just sail with the main.
That's reassuring, thank you. I just need to push it harder and see how far I can go. On the very few gusty days here so far she really takes off, heels a lot and I usually wuss out and let the main sheet out to round up. I doubt I have been close to being knocked down yet really. Need to find someone experienced around here to go out with me, then I would feel better. In the meantime (tomorrow) I'll try and worry less about it.
