I'm so tired of it...so unhappy that I'm barely able to focus or get any work done. No matter what I do I feel belittled, talked down to and misunderstood. I'm not sure what to do, I wish I could just leave right away. Should I tell my boss how I'm feeling?
If I was getting belittled in my workplace, I would discuss the issue with my boss and clarify the misunderstanding.
However, every boss is different and approaches situations to their own terms. It all comes down to how your boss is.
I did this once to my supervisor and they understood the situation. I resulted in quitting though because they didn't reduce the faults that laid in their company and continued their poor management.
Hope it works out for you, wish you the best my friend. Life is hard, do what you got to do.
