From childless couple to suddenly raising my sister's kids. Life is unrecognizable.
My sister passed away 18 months ago and we took custody of her kids, ages 7 and 10. We were never planning on having kids. Our house was peaceful, our schedule was our own. Now it's homework, dentist appointments, custody stuff with their dad, therapy. Some days I feel resentful and then I feel guilty for feeling resentful. My wife and I had to completely restructure everything. But these kids needed us. I miss my old life but I don't regret it. It's just a lot.
You weren't planned to be their parent but you stepped up anyway. That matters so much more than having nine months to prepare. They've already had the worst loss imaginable and you caught them. You're doing better than you think.
