It was nice meeting you as well!
Anxiety as a symptom is part of many different mental health issues. OCD is actually one of the major Anxiety Disorders.
It only becomes serious when it interferes with a persons day to day life. There are many techniques one can use to minimize it if it is not at such a severe level. If severe one should seek the help of a therapist.
I am glad you were able to move beyond it...sometimes the anxiety or OCD is a manifestation of a specific acute situation and when that situation passes so does the fear and worry.
To your mental health!
