Your realtor "friend" is oportunistic for sure! Yikes! Sounds like she was after more than the chicken coop to me. Yes, I would never trust her to sell anything and make sure you smash your chicken coop to all hell if you ever sell that place.
A lot of men don't understand that you have to vent. And if you can't vent to them you'll vent to a friend. It's not against them. It's how a woman's brain works. We have to talk and analyse. Men fix. Women analyze. That's just how nature made it for some reason.
It's okay to be scared. But you can turn it into fuel maybe? You're a strong woman. You will get through this.
