Trying to get phentermine?

I was trying to get my doctor to prescribe me some phentermine diet pills....Ishe had me have tests done...my tests came out normal...then she sent me to a weight loss management program orientation..(which wasn't for me) cost for that program was like $4300..I was like no thanks....I emailed her and told her I didnt think that program was for me and if she can just prescribe me the phentermine...she was like no you have high bp (which I dont) all my test where freakin normal!!...she told me to try Alli...Umm I've heard stories about Alli and I dont think I want leakage!!!.anywho...How would I be able to get them prescribed to me?????
