Hi, Ruby, it's quite common for newly dx'd to be put on fixed doses for a while to reduce the number of variables in play till docs/dsn figure out your responses to insulin.
But it won't always be like that. After a while, once they get you clued up on figuring out the number of carbs in a meal and the amount of insulin to take for that, you can basically make your own mind up about what or whether to eat. It can be scary at first, a bit like driving a car on your own for the first time after passing your test, but once you get it sussed, it gives you a lot of freedom.
I can't be bothered with breakfast either, prefer an extra 30 minutes in my kip, and it hasn't done me any harm after 30 years.
But do stick to what your docs are telling you meantime, there's reasons they're doing it.
T1 can be a bit of a grind at times, but, longer term, it really shouldn't hold you back in any way. I've been away backpacking for months on end in Asia without any difficulties, so never think, "I'm T1 so I can't do this". Think, instead, "I'm T1, I'm going to do this, so what do I need to do to make sure I can do it safely?" More often than not, it's just a case of making sure you've got a ready supply of sweets at hand!
