I'm sorry OND I understand your sadness. I left home at nineteen and went to another congregation to pioneer. I have very fond memories of the lovely people in that congregation. When you're a teenager they can be very kind, motherly and protective. The kindness makes a big impression at that age.
Sometimes I too dream about that congregation, l wake up with a lovely feeling. It's just sad that they probably wouldn't speak to me if I contacted them now. Of course I can't say for sure but my pioneer partner from that town whom I lived with for a year doesn't contact me anymore so that gives me an idea.
It's rough I know!
