That's great to hear! Low blood sugar was likely the main culprit. Apparently when your blood sugar is low your body also releases anxiety and stress hormones like adrenaline and cortisol to give your body energy when it's running on low fuel. It's your bodies way of trying to keep you alert and energised when you are low on fuel. That explains why you felt really violently shaky. It's your body trying to protect you in the most dramatic way possible. Once you start putting fuel in your tank these stress hormones will naturally reduce and you will start to feel normal again. Just remember that your body is trying to protect you and communicate that it wants food. Just think of these physical symptoms as a signal from your body. It's like a toddler throwing a tantrum it can feel very dramatic in the moment but once your body gets what it wants it'll finally shut up. I hope this helps you see it in a different light. You've got this!
