An anxiety disorder brings about stronger feelings such as stress, panic and worry, these feelings can be constant or periodic but both are difficult to manage.
It might not always be clear what is making you feel anxious but it can affect your life in a way that might prevent you from going to work or wanting to socialise, avoid family and friends, these feelings can make you worry more about yourself and exacerbate that feeling that you are loneliness or confused about where to turn to for help.
