Wow! I can only imagine the disappointment you would've felt at that time.
I can't even believe your sister-in-law and uncle could treat you like that, some people are just so heartless. It was just so unfortunate you couldn't communicate with your family to tell them how you were treated.
I'm glad you didn't let that get the better of you.
My dear, the least people I expected to do such are close relatives but it's unfortunate
