memory loss and lack of concentration

[Saff]

Recently i havent been able to concentrate at all, have felt pretty spaced out most of the time, like ive had really vivid dreams and reality seems dreamy, my memory is fucked and time seems distorted. Is this shit normal for hppd? Im mostly worried as in may i have my GCSEs (big exams for 16 year olds). I just wondered if anyone else experianced this and how they delt with it if possible.  Thanks ? xx
