@Tjt, one of the most critical problems with depression is that  it interferes with a person's logic since it is essentially irrational.

For example, a person withh depression cannot say "well someone else has bene able to do x so I will be able to do x" because having depression means that you see yourself as intrinsically worse than someone else. You would say "someone else has been able to do x but I cannot because I am so much more worthless than that other person"

Usually with depression you have to approach things rather sideways in ways that deal with said depression. Eg "I cannot do x so I will do y" or "I cannot do x now so I will do x later"

so, while the positive reinforcement is appreciated, I suspect Shrike will need to deal  with where he is now before he can take advantage of it.

For instance before trying to work on hugely new skills in a public environment, try private ones?
Hell this is where playing games and persisting with them can help, since not only does one learn new skills through games playing (it was Kodp that taught me how to use vo on ios), but also when things are really! bad, very cerebral, logic based games can help a great deal.

Thanks again for all the empathy, encouragement, mental support, advices, and hints!

However, it seems You guys keep missing my actual, most severe problem, my current darkest fear, and the information I seek about it.
So this time I shall really try to formulate it as accurately as possible:

The information I seek is neither about blindness itself, nor about living/getting along blind in life.
It is actually one step beyond blindness, and I fear it is far worse than it.
I fear, that although I am starting to accept, and get used to my blindness, I will never be able to do so with that state beyond it.
In fact, I doubt I will ever be able to even cope with it, at least not without losing my sanity. (or is "common sense" the correct expression?)

Me, who still has a no more functioning, but still existing eyeball, with which I can "sense" the darkness around me, and another one without an eyeball, with a plastic prothesys on its place, can clearly experience the difference, that same difference, which is so difficult for me to explain to You here.

With my still existing, no more functioning eye, I can sense darkness around me, just like if a sighted person would get blindfolded.
With my other eye, which is replaced with the plastic prothesys, I can sense nothing at all, so no darkness even.
It literarily feels as a combination of dead skin, meat, and plastic.
So I only feel something is there, but it produces, it "emits" no senses at all, that's why I compared it to a glass-eye of a puppet, and mentioned the "total puppet" state and feeling, which is the one I fear so enormously.

So, my right eye is still a "sensing", living organ, while the left one is a senseless, "dead" one, I have no visual sense with it, not even the sense of darkness, unlike with the right one.
Just like with our hands or legs, those have no visual sense, so they cannot "see", visually receive, experience our surrounding, )regardless if it is colorful, black-and white, infrared, or total darkness), the very same is the situation with my left eye.

So the thing I wish, (and also fear) to find out now is, that after the eyeball-removal surgery, will my right eye become just as lifeless as the left one, will I be unable to sense even darkness around me anymore?
Will my head remain totally visionless, meaning without ANY sense of vision, like my hands or legs are?

Edit:
The misunderstandings are probably caused by my definition of "blindness".
Namely, "blindness" for me means "seeing", being able to sense only darkness around myself, while not being capable even of that, is an even far worse situation, a far more scary alternative than blindness itself!

Well yes...that's exactly what I am so scared of, that will make my worst fears come true...if you guys could only imagine, how fanatically I was protecting my only one, existing and functioning eye, how "abnormally" I kept guarding it all my life, all the time, merely to prevent this thing to ever happen to it...and it will still happen, despite all my, sometimes even paranoid precausion measures...

Anyway, thanks for the answer Dark, that figures, now I know all.
