Its not too bad man, you need to remove the little cover that reveals a screw behind the inner door release lever.
Its a torx if memory serves. This will allow you to take the handle off, next bit is gonna be tricky with the door in place, you need to pull the door card, you'll likely break a few clips but it'll come off, you need to spread the force over a wide surface area, a plastic spatula would likely do the trick.

Have you tried to lock and unlock the car a few times?
