My family pretends I'm something that I'm clearly not.

My dad and sister have been saying I'm very smart and possibly a genius. I'm really just average at most. My sister has been saying I'll probably win a Nobel prize in my life which seems absolutely ridiculous.

My dad and sister both are not stupid at all so I don't know why they're acting like this. I feel like it's just a way to compliment me. I obviously know them very well and it seems like they truly believe I'm extremely smart. I'm not some Einstein. I rarely get good grades and usually need a lot of explaining before I understand something.

It's been going on for a few years now and I really don't know how to deal with it. I've tried telling them that what they're saying isn't true and that they should stop saying it but it hasn't changed anything.

I now don't believe a single word of it when they tell me I'm smart. I try to ignore it and just want them to stop saying it. It makes me feel really weird and just uncomfortable.
