A relationship can be stressful, even when both people live in the same area, so a little distance can really complicate matters. But just because it may be difficult is no reason to think it is impossible or doomed for failure. With the right preparation and mindset a long distance relationship can flourish.
So often when people are anxious, depressed, dealing with relationship issues, or going through a life transition, their thoughts linger on what isn't right, their faults, and perceived weaknesses. Redirecting your attention to what you're good at and your strengths is a powerful step to bring about change.
