As pp's have suggested - try a shield plus hydrogel breast discs. We used shields for a couple of weeks as I had a huge oversupply & just had to wait for things to settle down.
I used to hand express just a little before a feed, seemed to reduce the engorgement & enable my tiny little DD to latch a bit better.
Best advice my LC gave me was to lean back in my feeding chair (or propped up in bed), put baby in the middle of my chest & just let her figure out what she wanted to do, plus I got to relax.
You'll get there! The early days are so hard - I remember crying every day at 5pm for the first few weeks. Stupid hormones.
