Hmm...
I would say personally i dont believe you are(a hypochodriasis that is).
because there are those that make them selves sick for attention, and then there are those who believe they are sick and really aren't.
From what you say, you are sick and have evidence that you are sick when you are. I've been called that too, but guess what? The doctors and parents and everyone was wrong.. A doctor finally did something more than a simple xray and CBC test, and guess who had termnal problems in their gi tract that was irreversable? yup, me .. with Crohn's.. The doc then said if they would of just tested me back when i started complaining of tummy pains, and such then the progression and damage and stuff could of been stopped and it would of never gotten this worse.
I would say just by reading what you've posted (tho i dont know you personally) that you prolly have a similar situation.. you have REAL problems, and REAL symptoms, and such...
That same doctor who found crohns told me "If a doctor EVER tells you AGAIN that you aren't sick, and you feel sick, and you know your sick, tell that idiot that he just hasn't done the proper testing, and hes a doctor so that's what he's there for. To test, and MAKE SURE you are healthy. Not just do a lousey CBC and xray! This could of all been prevented!" So.. I can't say if you have the same situation, but this is what happened to me....
And sounds like your mom might have some issues...
Maybe try asking her (if you can), something like "but you want me to live right? you want me to be as healthy as i can be right? I dont feel well.. something is wrong.. I need to be healthy again.. and there is only one way to do so.. And that is to seek out treatment. You do want me to be healthy... right?"
