<s>[INST] dear docter, a friend and i went on holiday this year. when somthing bad happend to my friend.he started going angry and mad. a day or 2 before this accident. my friend droped a florecent lamp on the floor and it broke. he accidently steped on the glass bare feet and one small glass went into his foot. and started bleeding . so he toke the glass out and continued walking around bare feet. do you think what made him in a mental state was becouse of the lamp glass that cut his foot and he maybe poisoned ? docters now think hes got bipolar disorder. but i forgot to tell them about the glass and the whole incident. [/INST] HelloI dont think the injury with fluroscent lamp could have caused bioolar disorder. Either the symptoms in your friend were present earlier but they were in mild state so went unnoticed or the diagnosis might not be correct becuase just getting angry does not mean that person is having bipolar disorder. Please visit another psychiatrist for second opinion.Thanks. </s>
