Hi Ametorpe,
This is a wonderful story. The tone is full of confusion and relief. It grabs all the reader's attention and makes them want to read on. The reader is wondering how Helen's family will react to her actually being alive. They will read to the last word to find out. The plot is straight forward and moves along logically. The story is about a woman who wakes up from a coma to find that her family thinks she is dead. The conflict is well defined. There is no doubt about what is going on here. The characters are well developed and believable. They come across as real people. The dialogue is well done and realistic. The characters speak like real people. The description is detailed and vivid. It puts the reader all the way into the story. I did come across one structural issue that needs your attention:

1) “you were with her for what? three years before the accident, plus the two years since she’s been on tubes.-Should read "you were with her for, what, three years before the accident, plus the two years since she's been on tubes?"

The story is consistent in terms of point of view and tense. You have accomplished a great deal in just a few words. Great job.
