I think you have guessed it perfectly right. Finally!!!!!!!!!! Thank you very much. Now could you please give the exercises for proper coordination of muscles.
Is it possible you can't look into the eyes of a person if they're close to you because the muscles of your eyes aren't working properly? It's very possible your eye 'focus' can be perfect - so that your eyesight itself is okay - but if you're muscles aren't working in a coordinated manner you may not be able to 'see' properly.
If that's the problem, there are exercises you can do to try to recondition the coordination of the muscles of both eyes. The exercises are slow, tedious and somewhat annoying - and you'd have to keep them up over time - but if that's the problem it is possible to work with the problem.
It is true that I am depress for some reason but I am really facing the above said problem. And whenever I have tried to ask for help I always get such responses. I accept that sometime this happens but what if you are not able to talk to someone because of this problem. I can't look into the eyes of the person if he/she is close to me.
Why is it you cry so often? Crying will not harm your eyes in any way, maybe just make them swollen and red for a bit, but that's all. You say you're an emotional person, are you maybe depressed? Depression can manifest itself in us in many ways, and fixation on a part of our body having a problem can be part of it. Once, while I was under a lot of stress, if I was looking at something with a design, the design appeared to to be in front of what it was actually on, and it became a very disturbning problem because I became fixated on the problem and staring at things and this would happen. Finally, I was diagnosed with severe stress and anxiety, put on meds and was fine. Today is I stare at something this still happens, but I think it would happen to everyone when stressing their eyes like this. I would accept that your eyes are fine, and move on trying not to dwell on it.
