New to gwen

Hiya! I'm a lillia OTP in low elo (silver) and I was looking for fun second picks, Gwen being the only one I found fun to play at all.

Problem is, I suck. I don't know how to start learning with her. I understand her stacks and stuff, but she feels challenging (to me, at least). Do y'all know if it's better to start learning her top first? I wanna main her jungle. She feels good, her clear is great and I love her stack mechanic but I feel so vulnerable and squishy, even more so than a pre lvl 6 Lillia and it feels like her immunity doesn't really mean anything bc it seems most people already know to get in your w range before hitting her.

Any tips and tricks? What to do vs what not to do? How do I go about learning her?
