They Told Me This:

During months 7-10 of my service, they told me I'd be going through this:

Month: 7-10

Issues:

• Slow work progress
• Language plateaus
• Cross-cultural frustration
• Culture shock

Behaviors/Reactions:

• Comparison with others
• Over-zealousness
• Homesickness
• Uncertain about adaptation/abilities
• Intolerance with host culture

Interventions:

• Reunions: talk with other PCVs
• Communication with home
• Simple projects: crafts, classes, meetings
• Consolidate host-country national friendships
• Review this sheet on changes

I'd say they were mostly dead-on in terms of accuracy. Kudos to Peace Corps for predicting my mental state!
