I think sometimes things happen in our lives, triggers, stressful things both good and bad, that make us tend to be anxious and have symptoms for no other reason than that they're there and our brain does that with them. And I believe there are times when it is just that simple, but we become anxious about being anxious and make a big mystery out of it.

You've got three things going on that raise stress levels even if they are positive things. Maybe thinking it is just a response to these things and focusing on being good to yourself during this time will help?
