Just diagnosed, feeling helpless

I am almost 27 weeks and I just got diagnosed with GD. I feel so hopeless and it is so hard to not get into my own hard. I ate healthier but also not super clean. I do get fast food frequently for lunch as a quick meal, and drink a soda every so often. I have been taking my readings 4 times a day & adjusting my diet for about 4 days now & I already feel so fed up & lost. I am a big pasta girl, which I know has other options, but still not the same. I love a potato, and I feel like I can’t have chips, mashed potatoes, fries, baked potato…. Anything. No sweets, which I don’t usually eat a lot of anyways but don’t get me wrong, doesn’t mean I don’t enjoy cookies or a sweet once every few weeks & I feel so cut off from everything. And my fasting numbers are high and I would feel guilty if they put me on medication. Does anyone have any advice or recommendations to quit feeling this way, or any tips to where they were able to enjoy their favs without being an issue?
