I've been like you just few days ago, when I started my own diet. Some people here helped me with their kind advice, so let me share some points, maybe something will help you too.
a) Look for a day when craving will no longer be so strong. Take your time and prepare yourself for that day. Auto-suggestion is the key for either success or failure here. Don't start too early, if you feel you are not ready to do it yet.
b) When you go, be ready to go "cold turkey". To get rid for good of bread, potatoes and other high carbs. Even if it would be for a while, prepare yourself for a lifestyle change, not just a temporary diet.
c) First week will be hard, expect this. Read about known side effects such as the "Keto flu", with transient hypos and loss of salt. Compensate with salt and vitamins (D, Omega-3, B-12).
d) Most foods have acquired taste. You don't like veggies because your mouth (and brain) got used with sugar and high carbs. Be very patient for just one week or so, and you will see results. You'll get used with the new taste and forget about the rest.
Good luck
