my hair is all dry and broken and snapping off at the moment because I have bleached it like crazy recently. any recommendations for good conditioners that I can use or natural things I can put on my hair to repair it a bit?

I'm actually very skeptical that you really can repair very damaged hair, and I think that a lot of people make a lot of money getting you to think you can.

That being said, The Body Shop makes a nice brazil nut moisture mask:

You put it on wet, unwashed hair, and you can leave it in anywhere from fifteen minutes to overnight. It smells really nice and it definitely makes your hair feel softer, even if it doesn't necessarily repair damages. And a little bit goes a long way.

I'm totally obsessed with my hair and over the last few months, have been using stuff 'for shiny hair', which really worked at first but then lately, I had felt my hair was starting to look dull and horrible and it needed a bit of attention.

Anyway, seriously, I just bought Tesco own-brand shampoo and conditioner, 49p each (for dry/damaged) (it's this reeeeeally blatant copy of Herbal Essences called 'Fruit Infusions') and have been using it every day and, whenever I have time, leaving the conditioner on for anything up to 30mins and have only been straightening my hair for, like, nights out (I used to do it every day) and I can see such a big difference already! And when I turn my head or whatever and my hair swishes, it smells of strawberries

You can't really repair bad hair damage. You can soften the stiff areas a bit with intensive conditioners, but since hair isn't alive there isn't any actual healing going on. I would recommend switching to a nice daily conditioner (Dove is cheap and smooths my frizzy hair pretty well) and avoiding products and heat styling. There's not much you can do besides do your best to keep it from breaking off until it's long enough to cut. I would really really suggest that, if you can afford it, you only get your hair colored in salons from now on. Color corrections cost more than initial colorings. It's worth it to have a nice salon job.

use olive oil. i completely fried my hair a few years back from bleaching and my friends mom who is a hair stylist said that olive oil would help it. and it did.
