The most common "quitting time" for new students in our dojo is a month or 2 after they get into bogu. The entire dynamic of training changes SO much when you begin training in bogu - many students don't like the shift. Some quit, and some work through it. I remember feeling so awkward, frustrated, and dumb. I had finally learned how to hold a shiani correctly and now I have stiff oven mitts on my hands and people are whacking me left and right. I would stick with it for a bit more - at least until you get more comfortable in your bogu. If you still hate it, maybe Kendo isn't right for you.
