Advice?

So, this is a home situation that I want to ask about.

Just want to note, yes I have actually studied this kind of thing, and have since I was very young. I always found sociology, psychology and philosophy easy and interesting concepts to study. So I know what I'm talking about.

Situation: My dad, without realizing, is fairly manipulative and accidentally mentally abusive at times. Now I know you're going to ask how someone can do that without realizing, and I think it's because my dad is a psychopath trying to be a good person. I'm not talking psycho like in the movies, but psychopath in the medical terms (Look it up, I'm not explaining it). I know he doesn't realize it, because he continuously says and does things that contradict. Like at one point, he's happy, and he likes spending time with us. And then another time he's yelling at us for each minuscule thing we do wrong (sometimes even when it's his fault). He might have bipolar, but I haven't studied that as much so I can't say for sure. 

Problem: This has slowly run me down over the years, luckily I had a strategy that resulted in me not even considering suicide or self harm no matter how bad it got. But I've recently started to notice differences in my behavior. Some more drastic than others, sometimes I have had panic attacks, other times I've shut down my emotions and been a drone. Point is, I'm starting to reach a point where I think I'm losing my mind. And my Dad isn't helping, every time he acts the way it does makes me feel worse. 

Solution?: My idea for a solution is running away and going to a city. I know for a fact that I could survive, I know how to live off of little to no money, and I know how to keep moving, how to hide well, and how to fight if the danger comes. The only problem is the fact that among my family, I'm the only one with a body that isn't damaged, and without a disability. So if I were to leave it may hurt my family.

I can go at any time, there's not really anything stopping me besides my will. What I know is that I can make it out on my own, and that it may help me figure out myself and maybe heal a bit away from my Dad. 

I guess there's not an exact question here, but moreso just asking for a second voice on the matter.
