Do I need an appointment sooner?

For the last couple of weeks, I've had blurry central vision. I made an appointment with what seems to be a really good ophthalmologist, but they can't get me in for a month. I'm really scared of losing my vision. I don't have a diagnosis of macular degeneration, other than from Dr. Google. Am I overreacting? Should I try to get an appointment with someone else sooner?

EDIT: They were able to get me in yesterday! It turns out I have vitreomacular traction. I'm still trying to understand that condition, but it seems it's not as bad as macular degeneration.
