I HATE BEING TOLD THAT I CAN'T DO SOMETHING...

I can do anything that I set my mind to...when I'm healthy...ok...I admit right now I am having a very hard time doing anything!...but that doesn't give anyone else the right to tell me that I can't do something...
I know you probably have no I idea what I am talking about so let me explain...
Yesterday, I sent an email to the U.S.Army on-line recruiter asking for information on re-enlisting in the Army Reserves as a Chaplain Candidate!  Last month I spoke to a recruiter at the SouthernBaptistConvention and said I could re-enlist as long as I got my MDiv and re-enlisted as an Officer before my 47th birthday.  
Now I know it sounds almost impossible for me to get my MDiv in less than a year...but I am sure that if I apply myself...and attend full time, I CAN DO it...anyway...
Today, I read the reply email from a recruiter at Ft Knox...telling me that unfortunately I can't re-enlist because of my AGE and because I don't yet have my MDiv. 
Well after reading that email, this morning, it just completely ruined MY entire day!!!
I HATE BEING TO WHAT TO DO!..AND I HATE BEING TOLD WHAT I CAN'T DO!!!... I KNOW FOR A FACT THAT I CAN DO ANYTHING!!!...So...when someone tells me I can't, it just send me into a FRENZY...I checked my blood pressure later this afternoon and it was ...are you ready? 196/106 P80!!!...
For the last year and a half, I have been told by everyone possible...that I can't do this...can't do that...no...no...no!...and I am just tired of it!!!...it pisses me off that I can't do what I want to do!!!!...I want to be in school, I can't....I want to be in the army...I can't...I wan't to be in a relationship...I can't!...I can't seem to get anything done...or ...do anything!!!
AND IT IS SO FUCKING FRUSTRATING...!!!!!   AAARRRGGGHHHH!!!!!!!!!!!!!
