Perhaps your symptoms only affect your life sometimes. You may try to rationalize them away, saying it's just an occasional thing and that you're not as bad off as people you see on television or the movies. You may read a lot of information on the Internet and decide that you don't have an extreme case of depression or bipolar disorder, and that you can handle it on your own. It's still reasonable to speak to a doctor if you ever sense something is wrong. It only takes a mild case of mental illness to throw your entire life off-balance, and even mild cases can be treated. Mental illness doesn't have to be a condition you endure.
You'll recall how you'll have spots in your vision that are sort of the opposite effect of what you normally see. That kind of thing will happen if you look at the sun for an extended period of time. It'll feel a bit weird as your eyes recover from that. It doesn't mean you've hurt yourself. It's just that you've overloaded some of the photo receptors, and it takes a while to get back to full function. In most cases, it's going to be just a few minutes. There's no lasting damage from that. You would have to be staring at an extremely bright image for minutes at a time before you started to get any clinically significant damage.
