Newly diagnosed T2: I don't think I can do this

I...was diagnosed last week, then hospitalized because my A1c was 10 and my sugar level 330mg/dl (sorry if I'm using the incorrect terminology). At the hospital it was easy, the food was prepared for me and made for diabetics. Right now I'm back home so I have time to think about it, but I'm going back to work next Monday and that's what scares me.

I never ate breakfast before. And at work I'm hyperfocused so I just ate what was there or got macdonalds. I can't imagine getting up early to cook and eat in the morning, or preparing food in advance for lunch at work (where I work doesn't have diabetes friendly or low carb options).

I.........dont think I can manage this. What's the worst that can happen if I eat normally just...much less than before and cutting out fast foods and sugary drinks? Can't that be enough? I've been obsessively googling and searching through this subreddit on what food I can and can't eat, and there is no consensus. I'm going nuts. And I'm incredibly anxious about eating anything other than meat and vegetables except I KNOW that's not going to last and also will affect my mental health negatively. Every time I taste a piece of bread it feels sugary now. I'm freaking out.

So, how bad can it be if I just...eat less, and that's it?
