Illnesses can take up so much time and energy out of your day that it's hard to have anything left over for anyone else. It could be your own illness, a partner's illness, a child's, or someone else's. No matter who needs caring for and who is the caregiver, it is exhausting. The drain is physical, emotional, and spiritual all at the same time. You're tired all the way to your bones in every way you could be tired, and it's hard to talk about. It either feels like a burden or feels like it's not worth the effort to bring up with others. Most people don't know how to react and act so awkward it doesn't feel worth the effort to get them to understand what this is like for you. You end up feeling so alone.
