I'm a mom of 3 boys, too! They're my world, I just love them!
Here's something that alot of people don't realize, when we get excited we have a surge of adrenaline just like when we get anxious, so of course we can have the tendency to have the same symptoms. Usually when we're excited it's about something positive, so we don't even notice the symptoms, we're not focused on them. As soon as we're anxious, we focus on our symptoms and how we're feeling. Adrenaline is adrenaline, no matter what, it's how you perceive it. Hope that makes sense. Don't be afraid of it, it's just feelings, you're not going to have a nervous breakdown. I'm sure you've experienced the worst already. Anxiety/panic has a distinct patter and limits. It doesn't get worse, you can just prolong your symptoms by what you're saying to yourself. I wish you the best!
