today , in my school classes .. everything was going good ...I was normal ...but suddenly I feel totally blank for no reason, seems like I was attacked by so many thoughts and they were capturing me . for a second , I was totally blank ..and so different types sounds vibrates in my , something like vibration. may be due to last night I was so stressed , but I was okay in morning . I know ,it's so weird but I can't even half of what I had faced today ..it was so strange ...
