Feeling down

I got COVID for the first time this week after being extremely careful for this long. My family traveled for a funeral, which is the first out of three times during the pandemic we have decided to travel this far - first flight. It was a meaningful trip and we also had a lot of fun, so I don’t regret going. I don’t know when I was exposed because I also visited a clinical trial office masked, worked one day this week indoors masked, and attended an outdoor concert. I took a test before seeing friends and family, which was negative. Then, I tested positive two days later. The people who came over have tested negative after me though, so I hope that stays true.
I feel so guilty for exposing my family and also sad that I caught it this month.
