I feel like im almost constantly fighting my mind from drifting off into some made up worrisome thought, but every once in a while my mind will kick into overdrive and ill start thinking about the past and conversations that may or may not have happend. While this "overdrive" only lasts on average a week, it feels like im going insane of crazy, its literally unbearable. From what ive read online, anxiety is when your on the verge of a panic attack or having panic attacks regularly. Is what i have still anxiety? Or could it be something else?
