Do I have Schizotypal Personality Disorder?

I understand no formal diagnosis can be made over the internet. However, I'm wondering if I am Schizotypal and if perhaps you guys can give me some answers.

So, I'm very introverted. To the point where I do consider myself socially isolated. I do go to school and very rarely ever hangout with people outside of school (I just turned 17 BTW). I have social anxiety disorder. I am very self conscious about my looks to the point of where I do wear makeup (I am male). I don't hate having relationships I just really really really really suck at forming them.

Now, I guess you could say I have "magical beliefs." For one, and I hate saying or typing it because I feel like some kind of weird paradox will happen but... everything I say becomes... true... I hate typing it or saying it because I just have this weird feeling like a strange unexplained paradox will happen! Also, I often feel like a protagonist in a big book right now. I don't think there is anyone "reading." I mostly mean that in a more figurative way. However, I just feel like the main character. Everything I do is just my character. Almost as if it was written into me by someone. I don't mean main character like I'm the center of the universe or like in a narcissistic way. I don't think highly of myself in that way. I just mean... I feel like I'm in a book and that book is both figurative and real at the same time if that makes sense? It's hard to explain. But, it does influence my day to day actions. Also, I do experience "episodes" of very distributing depersonalization/derealization from time to time. For the last few weeks I was just waking up to it. But, it also has been subsiding now. I'm not having as many "episdoes." I have not even had any the entire week.

Also, yeah I do dress pretty horribly. I have not cut my hair in almost 2 years and I admit I'm super unkempt. My clothing is also very unkempt looking.

So, does this mean I am possibly schizotypal? Should I seek help for this if I am? It's not that disturbing to me if I do have it. But, I mean I'm not saying I do want to have it. I'd rather be normal.
