Thank you for your question and welcome to AnxietyConnection.com.
I am not a medical professional and would not be able to give you medical advice. You don't mention in your question whether you are currently under the care of a doctor for your anxiety. If not, I would urge you to speak with your doctor. It certainly sounds as if your anxiety is interfering with your life.
That said, it would be impossible for me to say what is triggering your anxiety. Sometimes, when anxiety levels are so high, the anxiety itself, or worrying about being anxious, is a trigger, causing a never-ending cycle.
Jennifer Fee, Psy.D., in a previous post, wrote, "while anxiety may appear to come "out of the blue," actually there is always an underlying cause or "trigger." We have actually covered this topic a number of time as many people have a difficult time identifying triggers to anxiety and this is such an important part of an effective treatment plan.
I am giving you some links to posts on this subject:

I hope this helps
