I read this today and think it's a great article and wanted to share it with all of you. Lots of great info. Link to the article is at the bottom of this post.
Any transition serious enough to alter your definition of self will require not just small adjustments in your way of living and thinking but a full-on metamorphosis. I don't know if this is emotionally stressful for caterpillars, but for humans it can be hell on wheels. The best way to minimize trauma is to understand the process.
The Phases of Human Metamorphosis
Psychological metamorphosis has four phases. You'll go through these phases, more or less in order, after any major change catalyst (falling in love or breaking up, getting or losing a job, having children or emptying the nest, etc.). The strategies for dealing with change depend on the phase you're experiencing.
Phase 1: Dissolving
Phase 2: Imagining
Phase 3: Re-Forming
Phase 4: Flying
