I had the perfect life and gave it all up.?
If it was perfect why did you give it up? It must not have been perfect then. Nostalgia and "grass is greener" thinking are coloring your judgment about how things really were. Cultivate inner happiness regardless of circumstances. Practice feeling gratitude for what you do have, even if it's just the eyes to read this. In time your inner feelings will be reflected by outward circumstances, but if you try to change the circumstances to create the feelings you become trapped in an endless cycle of dissatisfaction.
