It can be a tough fight. I don't remember a lot about it: Its been years for me. But I see you're using sharks. One thing I like to do when I'm struggling with a fight is to use two foods in combination (You'll need to keybind for this)
So I would use, for example sharks (or rocktails or sailfish) in combination with a saradomin brew flask. Then you could eat one of each at the same time. IF you're not running out of food, but simply taking damage too quickly, you can also eat a jellyfish at the same time (green is much cheaper atm, but it will depend on your budget).
That's the main tip I can think of. I'm sorry that you've been stuck so long. It sounds frustrating.
