Thanks, coincidentally, I listened to a podcast episode about RSD (assuming you mean Rejection Sensitive Dysphoria) this morning and yeah, it is absolutely real. He's extremely sensitive to criticism, which often results in a vicious cycle. Will try to work with Minecraft to give him more topics. So far, he didn't like the whole Redstone logic stuff, but maybe it'll come in a bit. His mathematical abilities are actually quite good (and so are his language capabilities).
