Time, time, time.... Your fiancé needs time to heal. 1 year ago my mother had a hemorrhagic stroke that left her paralyzed on the right side, unable to swallow or do anything for herself. Today my mother's weakness on her right side is almost undetectable. she is eating regular foods, and walking around with a walker. The best thing you can do is get involved and learn as much as you can about her specific stroke and what to except. Use them for a guide, but remember everyone heals differently. I remember my mom did the same thing to me....When I asked her my name she said big nose. The trach may have to stay in for a bit, until she gets stronger. At some point they may give her steroids for her lungs to help ween her off of it. Things WILL get better she just needs time and your love and support. God Bless her.
