Am I a joke, or is it just me?

I believe I internalize a large amount of my problems because I never had an outlet for my own insanity. I have been holding back for as long as I can remember because every time I say something I am serious about, everybody else laughs. Are my problems funny because they're not really problems or because they're my problems? I never even get a straight answer to that question because they laugh it off too. My whole life nobody has taken seriously the problems that I consider to be important. Nor have they taken seriously my ideas, my advice (both requested and volunteered) my suggestions or my requests. My life has been a series of rejections and laugh fests. I could go to a comedy club and talk about engineering to a crowd of laughing hyenas. I'd be the top act. So is it funny because it's funny or is it funny because it's coming from me? Once in my life I would like a straight answer.
