Eye Twichting

A couple times a year, I experience eye twitching. It's rather annoying, but I guess there's not really much you can do about it. Some say it's stress, some say it's fatigue, some say it's your genes. All I know is that I wish it would stop. I can't find any reason for this to be happening. I get 6-8 hours of sleep every night(sometimes more) and I don't have an enormous amount of stress happening right now. I also heard that it could be anxiety, which may be the cause. If you know my current situation, then you know I have some reason to be anxious. I just feel like taking a pen and jabbing it in my eye to make it stop. I guess I just have to wait it out. If it keeps persisting, then I will talk to my lovely eye Dr, who is always so willing to help me.
