Self portraits tell us deeper things about ourselves then we can know through simple introspective thought. This typically applies only to painted portraits, but I think the same can be said for photographic images as well, if done right.
For this I simply played with some long exposure trials in my dark bedroom. I moved the camera a bit during the exposure and I think it must have captured an LED light on my computer which resulted in the red streak which makes me think of a tear. Pretty fitting for how difficult life has been recently.
Plus I just look tired, which is completely how I feel now. Tired. And done.
