Okay, a few things.
One, it would be better if you pressed replace all your "-" with new paragraphs. In English, whenever you have someone different talking, you start a new paragraph. So the first paragraph would look like this:
- "Mother, he is opening his eyes".
- "Thanks Heavens, my son is alive", said Marsha coming to the bedside where a youth was lying. He was of average height and sturdy. Strong muscles of his body and several scars indicated that he may have been a soldier.
- "Mother, you have to admit yourself, this is not your son. This is not my brother Mat, who was lost in open sea last year. Mother, please..." Adell couldn't continue, as tears poured from her eyes. She was worrying for her mother. Her mother once was a cheerful and '...' woman. This past year made her age very quickly and now she looked twenty years beyond her age.
"..." could be filled with intelligent, as she may be going crazy, which means that before she was probably not crazy, or in other words, intelligent. And I know that intelligent isn't necessarily the opposite of crazy, but sane is too direct. You want something a little more subtle.
That being said, I look forward to the next section!
