Disorder or fake?

Question

For some reason I kinda want some sort of diagnosis... not sure why, I just do. So... I suspect I have some sort of mental disorder, but then I start suspecting I'm faking it... then I have another attack that confirms it but then I doubt myself again... is there something wrong with me? Am I crazy or something? Do I have some sort of personality disorder that causes it? and if I did have something, would it be bad enough to even matter? Does it really effect my life? I mean I do have silent breakdowns in school that I have to hide but... that's normal, right? Almost bursting into rears because you did the question wrong is normal, right?
