First, Lifehack.org recommends being grateful for what you have when you're going through a tough situation. Although this may be difficult to do, being aware of what you have (despite the adversity you're facing) can immediately boost your mood.
Next, PickTheBrain.com notes that it's important not to wait for happiness to come around the corner - only you have the ability to change the situation and improve your own outlook on life.
Finally, try complimenting someone around you. Although this might seem a bit odd, doing so can take the focus off of yourself and your situation.
Don't hesitate to speak to your psychic if you're still having a hard time seeing the silver lining. A tarot reading may reveal that the issue is bound to improve in the near future, giving you peace of mind.
