Hello,Medications are expensive and so are tests. Often they are needed if things are not going well and affecting how you live your life. It sounds like you may be at the point.
Along with medication for anxiety it helps tremendously to have a therapist or a group to meet with.
Most importantly is that you share your story. There are many who will understand and support you through this. Please write again and let us know more about you. I will be awaiting further words from you.
You may also choose to check out our Resources at the top of this page as there is a wealth of information that may be just what you need.
