Agoraphobia & Social Anxiety Support Group
Agoraphobia is an anxiety disorder, often precipitated by the fear of having a panic attack in a setting from which there is no easy means of escape. As a result, sufferers of agoraphobia may avoid public and/or unfamiliar places. In severe cases, the sufferer may become confined to their home, experiencing difficulty traveling from this "safe place."

It's awesome to hear that you felt great after your walk! It sounds like you found a solution to help you de-stress. Sometimes relationships with our parents can be tense. Open and honest communication is important. If you need additional help, I have some great sources if you're interested :)
