Missionaries love people but can struggle with loneliness, especially within the first couple years as they are learning the language and starting to develop relationships. Loneliness can be very trying.
There are days when you want to hop in your car and drive away. And just keep driving until you either reach home or the closest airport to take you home, no looking back. To return to people who will receive you with hugs in a place that is familiar. I can't count how many times I've had this thought.
Homesickness can strike at any time, over any little thing. For example, taking your car to the shop and being frustrated over not fully understood or not being able to fully understand the mechanic. Will my car actually be fixed? Will I be ripped off? Does it have to be so hard?
The first year of ministry is the hardest and often the worst.
This is all I can come up with for the time being...definitely a "Debbie-downer" post.
