Just booked a solo overnight trip and my brain won't shut up about it

I'm going fishing in Lake Tahoe next month for just one night - something I used to do all the time before kids. Wife is totally supportive. But my anxiety is already running scenarios like "what if something happens to one of them" or "am I being selfish" or "they'll be fine without me for 24 hours why am I even thinking about this". Anyone else struggle with guilt about taking time for yourself?
