Anon I've had type 1 since I was 8yrs old. Some general advice:
Don't get complacent. Keep your sugar down and your A1C stable.
Bring snacks wherever you go incase of low, this is doubly so for doing /out/ stuff
I've been /out/ for a while. Now I use a pump and a site usually lasts like 3-4 days but I'm usually not staying out for longer than that. If I am? Bring a set change and insulin stored in a cold case or pack.
If you can get a sensor, get one. Super convenient. Super helpful. Very useful when /out/.
And lastly: you'll get used to it. I promise. But realize that eating for you isn't cost free now. You gotta know what you're taking in.
Besides that, best of luck to you anon and stay strong. You're living in the best time to be a diabetic in history.
