Am I overreacting...

I'm 17, and there's this uncle who owns a cow, so I go almost every day to get fresh milk from their house which is in same colony. But lately, I feel uncomfortable when I’m there. He talks to me a lot, but I feel like he keeps staring at my chest.. I don’t want to tell my mom because I already have so many restrictions it’s suffocating, and I don’t want more.

So, I ask my older brother to go instead(I didn't told the reason) so he teases me and thinks I’m just being lazy. I don’t know how to tell him the real reason I don’t want to go anymore.. Maybe I’m just imagining things, but it’s just... uncomfortable.
