I am a thirty-year-old working woman. I have been harboring unrequited feelings for a male colleague I met at work for over a year. He is always kind and warm toward me, but I have no idea whether this is simply his personality or if he has special interest in me. This constant uncertainty leaves me feeling anxious, and whenever I encounter him, I become so nervous that I can't speak properly and only end up regretting it afterward. I want to express my feelings honestly, but I'm afraid he might find me burdensome or that our relationship might become awkward, so I find myself unable to do anything. This frustrates me deeply, and at the same time, I'm growing weary of this prolonged one-sided love. How can I handle my emotions in a healthy way and find the courage to act in this relationship?
