Hi Dexter, I hesitated to post but am going to anyway. Solely because it might have been something that would have helped me if I had learned it at your age as it is too late for me, which I presume is younger than me if you are in school.
You obviously have emotions if you need to drown them- and yes your sorrows will learn to swim. And it is very true that trauma strips us of much and creates challenges others may not face, things others take for granted. I'm also not sure if the lack of interest in 'banality' or low tolerance for un-truth will ever go away- juxtaposed to our lives experienced I really don't think so. And yes, we are all pretty aware of how scary many people can be, or not good for us or to be around, dangerous or uncaring.
But, you have a big advantage knowing it's ptsd and though you haven't found relief yet you will find some, much by your own efforts. There's certainly nothing wrong with being true to yourself, you should be. You will also find it a harder go as you age if alone- less resources, less man power, less inclusion. Your motives may be challenged, you may be told you are good for nothing (as much of anyone's worth is defined by their roles.) You won't be accepted or 'acceptable' in many environments, and you will likely be forgotten (which is preferable to some of the treatment. ) It isn't pretty to get to the end of your life having no one care about you, either, although that has less bearing than the care you may give. I just watched my neighbour go out by ambulance, not sure if he died. He too had no one to care for or about him. I know he was too traumatized. I think he may have died. I was just talking to him by chance a few days ago, he was going to buy an older rescue dog because 'he didn't know how much time he had left', I think he is about 50.
I would have less to regret now if someone had told me a sense of a fore-shortened future doesn't guarantee a fore-shortened future. And I would have maybe allowed those who at least thought they loved me (and were decent) do so, and built a life.
You have more options now than it feels like. Don't give them up. Because by the end, going back to abuse or being used can feel no worse than a life lost, sometimes. JMHO.
