I have an appointment

I have an appointment with the doctor tomorrow. I don't know him, I spook with the secretary, she was very kind, I was nervous and I'm worried I wasn't polite because I didn't talk more than the necessary, it always happen to me. 
I'm much better than last week, my monday was very nice and I hope everything goes as good as today for the rest of the week. Still have problems, who doesn't? But really, I can't ignore this just because I'm okay now. I'm finishing my projects, I'll start my job hunt next week and hopefully until the second semester of the year I'll be able to move out this house. 
I'm very upset I'll have to leave my brother, he is like a son to me. He is six and my father is always trying to make him hates me, so I'm afraid that when I leave he'll forget about me or start hate me, because I'm sure my father will use the situations against me, he'll say to my brother that I left him and make him hates me. But that's not my biggest worry, I really fear that living in the same enviroment I grew up in, he'll have also issues and I don't want him to be alone, I don't want nothing to never happen to him, but if it does I want to be there for him, to support him always. 
So, I'll leave this house, but I'll make it always clear that he can live with me whenever he wants and never stop being his friend.
