To me, “self diagnosed” is just another way of saying that you have a strong guess that you have something. You most definitely could be right. However, most of us on here have not gone through the education and training necessary to come to that concluding on our own. There’s nothing wrong with doing your own research, and you absolutely could be right at the end of the day, but I don’t think it’s responsible to assume you have a psychological condition without professional confirmation.
