I have an eye twitch/tic and I hate it. There's really nothing I can do about it and I can't take medication for it. But what I hate more than my twitch is the response people, physicists in particular, have toward it. I present well, but I almost always get docked points because my "presence" isn't that great due to the twitch. I stand tall, I don't fidget, speak well, etc. but that twitch gets me down. I watch videos of myself, and if I didn't have that twitch, my presentation would be so much more enjoyed. People have been very rude ("Are you winking at me?" when I'm presenting a poster to them) and it makes me worry about my future in the field. Do you have any suggestions on what I should do to be better respected in graduate school so that my professors at least understand? Should I just inform them upfront about it? What about when I TA? I frequently get mocked by a student or two when I'm in front of a group of people. What can I do to make people see past it when I present my work? Am I "doomed" with regards to presenting?
