I would advise you to go with what feels right for you. It's your life and your body. Some people like to jump in totally, some prefer a bit at a time. Some hate having to measure or write up anything and some are lost without it. You've said you
so maybe just take a couple of weeks to get used to the way of eating. If you find you are eating more then maybe that's what you needed.
feel like counting everything just makes me obsessed and even at times, eat more
Um... 58kg for 5'7" is fairly slim... I'd actually suggest you go for size/shape rather than a weight on the scale. Although a kg of fat and muscle weigh the same, the muscle takes up less space, so remember that the scales are actually not such a good guide but a tape measure or your clothes are your friend.
If you know you have a low carbohydrate threshold and you want to lose weight then that won't really change for you, except that where Atkins allows 'chemical' alternatives (like artificial sweetener) to keep carbs down, you'll be avoiding them. The other big thing will be to get over being 'carb phobic' as there is nothing to stop you eating up carrots or beetroot or pumpkin or nuts or even fruits except for your appetite and your measurements. If you find that you aren't getting the progress you want, then you might have to cut back.
In my case (as you asked) I mostly eat fairly low carb (50g or less) because I'm pretty small (157cm), I naturally love leafy greens and salads and grow a lot of that stuff so it's easy to get, I don't tolerate large amounts of stuff like pumpkin and I don't eat dairy or sweeteners for health reasons. That doesn't mean that I won't eat high carb meals simply because they are high carb, but I do pay attention to how my clothes feel and I have had to cut back on fruit/nuts from time to time.
