Well yes, you're new. There's a lot of small nuance to take in when you're learning the game. If you want to improve, not just at videogames but at anything, you only need the knowledge and the practice. Get others to help you out with the knowledge, there are a lot of resources out there (such as the people in this very thread!) and then practice until your eyeballs bleed.

For another tip for staying alive as any melee, I'll tell you to always be aware of your line of sight to the enemy. Whenever you can line of sight someone you are taking 100% less damage from them, and anytime all five enemy team members have line of sight of you is extremely dangerous. Play very close to walls. Duck in and out of corners between your weaponskill GCDs to cause enemy ranged's casts on you to fizzle. This even applies when you're on the crystal and pushing it; you don't need to be in the middle of the crystal, pick an edge close to a wall that doesn't let the enemy ranged hit you unless they come closer and put themselves at risk.
