Many people have irrational fears that they are overcome with and shoulder for the entirety of their lives. Recognizing that your fear is an issue is the first step to conquering it. The next step is realizing that your fear is unrealistic. Seeing this will hopefully help take some of the power away from your fear. In your particular case, I surmise you are afraid of falling into a storm drain, which is nearly impossible given its size and placement. I know that probably does little to calm your fears, but storm drains really are quite small, and are difficult to fall into unless one is toddler-sized and purposely attempting to do so. Whatever the case, a fear is a fear—no matter how strange—and facing it will require some real bravery on your part. I’m sure you will have no problem facing this problem!
