I was on a camping trip with one of my friends. During this trip I was going through a crisis trying to figure out if God wanted me in the Catholic church. While walking near to the campsite (which was a 3 mile walk from the parking lot) we noticed medium sized identical sticks perfectly arranged to make a triangle like shape. We both thought it was very strange and commented on it but went on our way.
Later as I tried to sleep I had one of the worst headaches I've ever had. It was accompanied by tooth, ear, and if I remember correctly throat pain. Most likely because of the long hike, little water, and very low temperature.
As I lay in my tent I clutch my rosary and pray that this pain can end, as I had no medicine and did not want to waste what water we had left. Eventually it went away, after asking for Mary's intercession. And praying directly to God.
In the morning I read some of the Bible and while my friend was walking around the site, I pretty much begged for God to tell me where I should be. Answer and tell me how I can do the most for God, I felt lost, abandoned, all I wanted was to live according to the truth, I just wanted to know how, and to know if Catholicism is that truth. I just wanted something so I could know I guess, I was already led to the church but I kept doubting.
Later as we walked back to the car (still near the campsite), the same type of identical sticks we arranged in a shape of a perfect cross. It was close enough to the campsite we likely would have heard anyone else. Plus the chances of anyone else being there were extremely low, as someone would have had to be in the middle of the woods at night and be gone in the morning.
In the same vein I remember before I entered the church, I prayed during and after mass for God to guide me where He wanted me to be. To help my doubts of entering Catholicism. After one particular time, when I was feeling especially lost, a lady whom I'd never met approached me after mass and told me how happy she was I was there, and hoped to continue to see me.
