During that break, you may have a eureka that you are at the wrong place, or that you just needed this rest, an attitude adjustment. And a plan of attack, a positive attack. For example, job advancement or an excitement about your job may just percolate up, even though I've suggested you not to specifically think about your job. My former boss played favorites. Even though I was on her good side, it made me very uncomfortable to see how she treated some of the other people.
Truthfulness is still often the best policy.
Well, it's certainly been a pleasure having you by today. There's so much. First by communicating with that boss, and finally, if all else fails, looking for another job, hopefully having learned something in the process, so the pattern isn't repeated. Hopefully they also have a heart, and ears that can understand. Take the risk and talk before you walk.
