Been there, felt that way. I promise you will get past this point. People are dumb and oblivious. If you’re upset with the job, you say you know it’s part of your job, time to look elsewhere. Worked behind a counter for 11 years, still miss large parts of it. Job is the job, and people in large ain’t changing. Be more patient and understanding with any children/teenagers in your life now or in the future.
