First of all: Welcome to the forums!
Some basics first: Resistances are very important in Grim Dawn. That’s one of the reasons you’re struggling with your character. Try to get as close as possible to the cap of 80% with every resistance type. Later on, you even want to “overcap” resistances. Stun res can be lower - depending on your build and playstyle. But everything else should be as close to 80% as possible.
Having for example 17% Aether res (Im using the value for Elite difficulty here) will get you killed by practically anything that does Aether damage. So you should definitely look for gear with more resistances on it.
You should also start using components in your gear. Look at the components you have in your stash or at the recipes your Blacksmith has learned. You’ll pretty sure find something to improve your character. To get better Aether res, you could for example use “purified salt” on your weapon or on an offhand item. A “silk swatch” will get that super low pierce resistance up. “Antivenom salve” gives Acid/Poison resistance. And so on. If you got problems with energy regen, look for “Ectoplasm”. You can put it on rings, medals, necklaces and helmets. It helps a lot. Use those components - they are meant to be used.
Regarding gear: Your main damage source is lightning. So anything with lightning or elemental damage will be useful. Also boni for skills you use are nice. Looking at your GT, you’re already going in the right direction regarding damage stats. But you need more resistances. Blue items may be tempting, but especially during leveling, they come with rather few resistances.
Currently, you’re definitely wearing too much blue without sufficient resistances. Green items can roll lots of resistances. That’s what you should be looking for. I’d also recommend replacing that yellow shield with a proper caster off hand. Among other things, they usually have energy regen on them - something that would definitely help you.
Unfortunately, I can’t help you much with skills and devotions. I don’t play Druid myself and I never leveled one. But maybe someone else can help out.
EDIT: Some of my points were already mentioned. Sorry. I should learn to type faster then…
