Anxiety doesn't always begin "naturally". Sometimes it is the end result of years of abuse, whether it's mental/emotional or physical. Be gentle with people that have anxiety issues, you never know what their story is.
Just what are anxiety disorders anyway? Anxiety disorders are the commonest psychiatric illnesses globally. And while there is no cure for anxiety disorders, there are very effective treatments available with a good evidence base.
Things not to do when dating a girl with anxiety. 1 - do not wait hours to text her back, thus leaves room for her anxiety to kick in & her mind to over think. Over thinking kills her confidence & jeopardizes your relationship just based on what she is thinking. 2 - do not ever let her think she is unloved. Whether it's a simple goodnight text or a random compliment, these little things put a person with anxiety in a more relaxed state. 3 - do not poke fun at her illness.
