I can relate to this, I stopped being a NEET over a decade ago now but it happened to me, I just told them how I felt and let them be after that.
At the same time, when I was a NEET I didn't like at all when people came to me with their ideas of self improvement and health, so I understand them too.
In the end they made it too. I think simply seeing me get better helped them.
The NEET who look down on people who get out of it exist, but I don't think it's a product of being NEET, I believe they'd be as lame as non-NEET.
