Some thoughts keep coming back no matter how sensible you are about them. The email you have reread five times. The same argument replaying at two in the morning. The task you have put off so long that starting it now feels worse than avoiding it again.
CBT works on that pattern directly. Sessions happen by secure video, so you can meet a qualified therapist from your sitting room, from the office once everyone has gone home, or from anywhere in Ireland with a reasonable internet connection. No commute, no waiting room, no explaining yourself at a reception desk.
