Hello HugoSpaans,
I felt that exact feeling at the beginning/onset and I would like to tell you with certainty that you will not lose your sense of self by not hyperfocusing on it. You're okay. It's just traumatic to have your entire perception altered and you're just worried it could get worse. "If it can get THIS bad couldn't it get worse?" But the answer is no, you're fine. You just gotta repair some variables and you'll be 100% again looking back on "that time period where you HAD dpd/drd".
