I read some online articles about cancer drugs might treat autism. Because I had cancer these articles recalled my change in social behaviour after chemotherapy. First year or two after chemotherapy usually introverted and asocial I that avoids social occasions became extroverted and wanted to hang out despite being a little odd. But in the last year or two, it is back to old again, introverted asocial and with social anxiety. I wonder if the chemo really made a change in my brain that made me sociable. Or maybe just adolescence because I was 14 and 15 in this social phase (now I'm 17).
