run: the best self-defense

One morning at my campus, my professor was fixing his things before the lesson. While he is doing that, for some reason, he asked the whole class, "What is the best self-defense?". Then of course I answered, but with whole regret I only said it in my head. I said, "running". Apparently that's what my professor also believes to be the best self-defense. I am on my senior year on high school. It is my LAST year on high school. OMG after 6 years of labor and hardwork. Everyday I travel an hour just to go to school, where there are true people and of course ugly and fake people. I usually wake up at 5:00 am but today, January 23, I accidentally turned off my alarm and woke up at 6:30. It is a very horrible feeling and situation. Like how am I going to prepare if my classes starts at 7:00 am?! For sure I'll be late for like an hour today. So what should I do? RUN! I got up in my bed, wore my uniform, I actually didn't I wore an outside attire because why not, combed my hair, which I actually didn't do also because that's too time taking, brushed my teeth, yeah I did that, then rushed to wear my favorite snickers then went outside and locked the door because I am sure I already have my things and my key in my bag then slammed the door. Which is actually my biggest regret in that very moment because I haven't washed my face yet! So I rapidly opened the door and ran to my bathroom washed my face, put on some sunscreen, and some lip balm. Now I am finally ready to go. I guess this day is really not my best day. It might actually be my worst day. I ran outside, locked the door, ACTUALLY locked myself out. I forgot that I put the keys on the table while on my way to the bathroom! What should I do now? Should I still go to school?
