-sends you all the hugs- I wish you the best of luck in getting on your own feet, and then your family can see where it leaves them ::/
Ok, so your brother is being seriously inappropriately controlling. Does he pay for the internet? If not, he has NO right to tell you how to use it. Have you mentioned that hes actively preventing you from being able to make money? Im assuming you know sexual assault by a parent is significantly more fucked up than him "not respecting you as a person", that is some dangerous shit and if you have any possibility of getting out of that household then id strongly suggest getting out. The facebook thing is also super inappropriate and also emotionally manipulative with the "i'll give you one last chance" bullshit. Any chance of setting up a private facebook you dont tell him about? Cause no he really gets no say in what you post as an adult. If you're mature enough to run his householf and be responsible for his daughter, you're mature enough to post shit online.
For what its worth, I still think these two have no idea what to do to help people get over problems. :/ But I have never been much of a fan of your family. Hopefully as we improve your support network you will have bigger buffers to when they pull stuff like this.
