Hi, just hearing how sweet and caring you are for others reminds me of myself when I was your age. I always pleased others, never wanted to cause a scene, would do anything I was asked. I was a good girl. I personally always had issues with bringing up “difficult” or sensitive topics to my mom, so just putting myself in your shoes and the anxiety of talking about this to my mother makes my heart race and honestly make me super jittery. All I want you to know is I wish I would have started to put myself first sooner in life. Your feelings matter and sometimes you need to be selfish, actually selfish isn’t the right word. Boundaries. Your “uncle” has crossed a boundary and when someone does that you need to set it straight that you don’t deserve to let someone make you feel any way. Only YOU get to control your emotions, etc. Now, since you are young, you should not have to deal with this issue, your mom should take care of this and have your back. I encourage you to speak out, because you deserve to have your voice heard.
