She is probably the toughest boss in the game, alongside Logarius and Gehrman, so no shame in getting splatted a few times. Ad7's vid will probably help, but here's my tuppence worth. Divide the fight into two halves: the first is the easy one, apart from the move when she rushes at you; the second is the harder one, unsurprisingly.
During the first half, lock onto her head and learn her moves (tentacle side swipes that you can easily dodge; tentacle front slam that you can easily dodge and get a cheeky hit in before she raises up again; blood-frenzy attacks that are even easier to dodge; and the dreaded charge attack which will probably bowl you over despite trying your best to dodge sideways) and bide your time until she gets exhausted and collapses headfirst in front of you, then you have time to use your powerful hold-R2 attack on her head. So best to get your attacks in after her front tentacle slam, and after collapse.
Once she's down below half her health, she goes into bastard mode, and creates a shimmering aura around her body that gradually eats away at your HP the longer you stay very close to her. Not a big problem though as it doesn't do much damage. The biggest problem comes in the form of two attacks: the first is the laser summon attack which sends three bursts of tracking beams your way. This is one point where you should unlock from her so you are free to run in any direction (not strafe), as just jogging consistently in one direction for the duration of the attack has the lasers land safely behind you; the second attack is her 'goes mental' one where it pays to be a good distance from her as she thrashes her tentacles about and can kill you easily if you are close.
If you find it too hard to safely land attacks on her during this phase (as there's less opportunity to do so), then there's a little bit of cheesing possible with her which makes it easier, as there are places in the arena where you can hide from her. A large vertical pillar on the left (from entering the arena) about half way, and a fallen pillar on the right (from entering the arena) about a third of the way. If you hide behind these when she's far enough away she'll slowly turn around and go back to the position she was in when you entered the arena - ie sat in the water facing away - and you can creep up behind her and get a power R2 move in on her and dash away to hide again and repeat. These hiding places also offer total protection from laser attacks.
