Here's the thing (which I'll type now as it's clearly not an emergency so I'm not worried about freaking you out into a panic anymore). You have T1 diabetes, which means you're at an increased risk of a number of brilliant and fun things. And, generally, we diabetics - whether T1 or T2 - need (as a priority) to look after our urinary tract - kidneys, bladder, urethra - which is brilliantly simple to do: we just drink water.
Yellow, oily urine isn't just a symptom that you're not drinking enough water, but that either that you're dehydrated or that you have a serious problem that is preventing your bladder from producing pee normally. If we're drinking enough water (to keep our precious tract happy) it will barely have a colour to it - even in the morning. It certainly won't have an odour, leave bubbles in the loo or be "brown". (And that's brown, I'm assuming, even after you've peed in the bowl which, I'm presuming, already had water in it).
How do I know all this brilliant stuff?
I used to be marvellously proud of how infrequently I needed to pee. I could go an entire work day, even finishing late, without needing to go once. 14, 15 hours of unbroken, peeless concentration. People used to think I was freakish.
The first I knew that I was ill, and not just ill, but seriously-and-about-to-start-fighting-for-my-life ill was that it was almost impossible to pee, and that my urine was brown and oily. Minutes after this, I was doubled over in agony.
I had developed kidney stones (the primary cause of which is... not drinking enough water), which had - as my amazing luck would hold - managed to block both of my kidneys at the same time. Which meant that my bladder couldn't fill, which meant that I wasn't able to rid myself of the kind of thing we really need to pee out with some frequency, which meant that my blood was now infected and I had developed sepsis and my kidneys were starting to shut down.
You tend not to do so well when your kidneys aren't working and your blood is infected; there's no quick way to get all that infection out. My toxin levels were going crazy because, shortly after I got to hospital, my liver had decided it had had enough, and then things start to get really crazy.
It took 3 surgeries, 3 weeks in hospital (spread over 6 weeks) and a further 6 months in bed at home before I could say I was "better". I haven't - and probably won't ever - recover to the level of health I enjoyed before I fell ill. At one point I was so ill I was in post-operative recovery for 24 hours while they discussed whether to put me in ICU in an induced coma or move me to the ward. It was also the start of the end of my ability to walk. I have a 50 / 50 chance of this happening again, and given how poorly I process pain (I'm typing this this - and moving house - with a fractured wrist and a completely degenerated disk at L5), I probably won't realise anything is amiss until I, once again, collapse and have to fight for my life.
All I had to do was drink water and pee regularly. These days I make sure I have a 2 litre bottle of water right next to me at all times, and that it gets refilled at least once every day.
The moral of my cautionary tale is this, and I'm not even a little sorry to be so stern: You are not drinking enough water - which is especially dangerous as you're a T1 and your kidneys and bladder are already enjoying elevated risk factors.
I say this with love to anyone whose pee is anything more than a vague yellow colour (even in the morning), drink more water. Drink at least 4 litres of water, every single day. Make sure you pee at least 3 times a day, and if, after drinking enough water to pee regularly, your urine is brown and oily, recognise you have a serious problem and get to a GP - again with love - not an online forum of strangers. And if my exceptionally cheerful tale isn't enough to encourage you, look up how they insert a "urethral stent", which you'll have to have if your kidney - like mine did - gets blocked with a stone. It's super-fun reading!
All those fantastic Morphine Dreams I had 3 1/2 years ago should count for something, eh?
