Sypheren, all the replies here have been useful, especially Sean's, and could have helped me a lot if I'd seen them when I was still wearing strong contacts. A few other things to think about:
Do you remember when your eyesight started declining, if there was something going on in your life you didn't want to see? (You can decide you're older now and strong enough to handle it, so don't need to limit your vision.)
Pay attention to what you CAN see clearly, even if it's close or big or bright-colored -- don't dismiss it. Your eyes know what to do and the more confidence you have in them, the better they'll perform for you.
Use the eye chart as an indication of how well you're seeing, especially noticing where you feel tension in your eyes and face. Don't use it to test yourself and make yourself feel bad because you don't see something clearly you think you should. Make sure it is close enough that you can see a lot of it clearly, or else you'll just be straining and won't be helping yourself at all. (Sean may have already said this.)
Remember you are learning to establish correct healthy vision habits, not "fixing your eyes". You need to practice the new habits until they replace your old ones, and like good posture or good eating habits, they will become more automatic until they're part of your normal way of living.
Don't get into the trap of measuring your progress on any timeline, just appreciate everything you see, blurry or not.
