In the midst of this emotional transition, listen to what your loved one has to say. You will likely find they have fears and anxieties, but perhaps also solutions that you can help enact. Listening is always important, especially now.
Having a parent that needs assisted living services can be rough for everyone involved. With a little work, and a lot of time together, however, you can make it much less difficult than you ever would have thought. Remember to listen and put in an effort to make this transitory time easier, and it will be.
