Failed at my first real job out of college how do I explain in interviews?

The training was supposed to last 6 months with a topic demonstrated on Monday and completed by Friday. I quit because I was about to get fired and regretted it immediately. I sucked so bad at the job I was horrible. I’m now a para at an elementary school making $9 less an hour. I was supposed to make $60K a year and lost it in 8 weeks. What do I do now? I don’t want to work my way up to be a teacher, I’m completely lost in life. I also got fired from a property management company this year, I’m so lost on what to do. How do I explain my short tenure at my first corporate role in interviews? Thank you.
