Kyle, I understand the situation. It can be really hard deciding on what to do after something so traumatic happens to you. You managed to get the courage to act. Well done. You did the right thing. I'm sorry your family is being the way they are, you do not deserve that from anyone, especially people that are supposedly meant to be there for you during even the worst times.
Family friends are only friends until they do something to break that trust, he broke that trust, believe me, he's no family and he's no friend.
With regards to your family, if you're up for it, I would suggest that you sit down and talk to the one you're closest with, let them understand the situation, talk it out calmly, it's okay to be emotional about it too though. Having someone by your side is all you need, even if it's just a single person. I'm not sure about your entire circumstances and why it feels like they're so against you but it's very possible it just feels that way and in reality, it isn't like that at all.
Sending you strength. I hope you manage to resolve things at home.
If you'd like to talk more, please don't hesitate to private message me.
