I Recently Ate A Pb And J Sandwich With Homemade

I recently ate a pb and j sandwich with homemade strawberry jam. The jars were sealed with wax, and positioned upside down to cool. Unfortunately, they were left in a car for a few days in high heat. I ate this yesterday in the afternoon and last night I awoke with sweats several times and in the morning had diahrrea and felt very faint. Could this be botulism.
