How to Brighten Tone of Announcement

I'm approaching 16 weeks and want to announce. This pregnancy was a surprise, has been incredibly difficult, and I am not happy about our circumstances, as I am too sick all day to work and we now cannot afford our basic bills without parents' help. I'm an introvert and don't want a hundred people suddenly giving unsought advice or calling on the phone, even though I know they mean well. I just want to get through this with support of my closest family and friends plus some internet strangers 😁. Anyway, I want to be honest about the difficult circumstances without causing too much concern or seeming like we are only sharing to seek help. Any advice or things to avoid? Please share your tips for staying positive. Thank you so much!
