Your Parkinson’s disease has you back under your parent’s roof.
You had no other option but that doesn’t mean you aren’t second-guessing your decision. It feels like you are a child again. Years of independence feel as though they have simply melted away. There is probably no aspect of PD more difficult than having to return “home” after spending many years away. However, this is not a moment of personal failure but one of necessity. Making it work may be challenging, but it can be done.
The greatest obstacle to successful transition back under your parents’ roof will be the natural tendency to fall into old behavior patterns. This applies to both you and your parents. After all, your interactions emerged and began to evolve the moment you drew your first breath. There is no one with whom you share a longer history or with whom you have the most deeply established relationship roles. Roles tend to define interactions and can be very resistant to modification even when circumstances change.
