I'm so sorry you're feeling low and for that stupid picture. I so admire you for even attempting to work full-time. And teaching is a challenging profession. My dad was a high school history teacher. Talk about the worst subject to teach to horny teenagers! It's a very demanding job and i'm impressed that you're equal to it. It sounds like you're dealing with your rowdy class in creative ways. I'm sending you good wishes and vibes. You're dealing with a lot of stressors -- give yourself credit and hang in there!
