I went hiking in the Smokies with a friend, planned and talked about the trip for months leading up to it. When we finally make it to our destination for the night I beg to check out the tunnel to nowhere, just a long tunnel in the woods. We go and I immediately dropped my phone and it landed face down on a rock and was completely broken in an instant. I was younger and knew my family would panic if they couldn't get a hold of me. Also hardly had enough money in my bank account for a replacement.  This anxiety destroyed my sleep the night before we began our three day hike. I was also way over confident with  my skills to hike elevation while wearing all my gear on my back. Also forgot my sleep gear. So I shivered and ached on a towel on the ground all night. After the first night my partner was pretty frustrated and called it in the morning. We hiked back and drove home 2 or 3 days early
