From one fellow autism-haver to another, I’m so sorry that your parents don’t treat you as they should.

And yea, the sentimental value with the silver is what hurts the most, but the most important part will always be with you. The memories you shared with your grandfather.

There’s a lot of neurodivergent people who grew up in similar situations, who managed to thrive in spite of it all. So don’t give up hope, you will come out of this stronger, and if you ever become a parent, you will be a much better one than your parents are.
