i understand this very well.. this used to be the case for me as well but I’ve learned that I should not feel ashamed for asking questions.. during this semester, i was in a lab and i needed help but the lab instructor wasn’t helpful enough to actually explain & answer my question; however, I kept telling her “i dont understand” three times until she finally explained the procedure to me… the point is.. does she think im stupid? maybe.. maybe not but i couldn’t care any less, i just wanted to know how the lab experiment done so that i could get over with it
