Hereditary??

I am 24 years old and I have had problems my entire life. I have always been overly sensitive; the smallest things set me off and I need to cry. I was diagnosed with general anxiety disorder when I was 17 and recently with extreme food sensitivities. My body reacts badly to certain foods and my immune system is very weak.I actually see a natural health doctor to help with all of my recurring ailments.

I hate crowds, I have a lot of irrational fears, including a phobia of dirty stickers. I'm a bit of a germaphobe and I've always been a really hyper and overactive child. Even now, I have a hard time sitting still for long periods of time and I constantly have to be touching something or engaging myself. I can't really just sit still. And so much more....

Anyway, I was just wondering if SPD can be hereditary. My nephew was diagnosed a few years ago, and my sister is convinced that I have it too. And looking at my family, several of us have similar odd habits, especially my father. My whole life I've just *known* something is wrong with me... that I am not normal, and my family just thinks I'm a hypochondriac. I know I'm not crazy, and this seems to fit for me. How would I go about looking for a proper diagnosis?
