Am I crazy? Am I wrong? Can I find Clarity?

So, I want to spin a tale of a recent (horrible) doctor's visit that I recently had. I'm not sure how many people will reply to this, had this happen to them, but it's been a few days and I still cry about what has happened and I'm not sure how to feel about it. I hope someone listens/ understands.

I was playing at a local game center with my friends to celebrate the start of summer classes. We decided to play this dance game (DDR) I used to be really good, but I haven't played it in years. So instead of trying to start slow, I went ahead and did a hard song, messed up my footing, and hyperextended my knee and sprained it. Afraid that it might be a serious problem, I went to go see the doctor at the college health clinic the next morning.

Before I continue the story let me clarify...

I arrive and I get weighed 192. I was shocked at that number because I don't weigh myself I measure myself in inches.
(for the story)
w:31
h:43
thigh:26
arm:13

I have been dieting since Ive been back from studying abroad and my inches were atrocious *w:36, H:47, thigh:27 arm:14
So by March *when I came back* I made a lot of good positive changes since then; no drinking, drinking 6 glasses of water *with my water bottle*, and eating what I want, but half of it which is how I lost those inches. Still a lot of progress that needs to be made, but I'm working on it.

But I actually get to the doctor and she says, "I see that you're here for a knee problem, but there's a much more serious problem underlined here" and I get confused when she says, "Really your knee got sprained because of all the weight you are carrying." I tried to tell her that I have been losing inches and told her my stats *which I measured myself the morning before* and she said, "I'm looking at you right now and I know you're not 31 inches" she then proceeds to "consel" me on how these an epidemic in America on Obesity and that I'm on the high road to diabetes. I kept trying to tell her my eating habits now and how I'm losing the weight, but she said, "If youre not going to be honest, then you're only hurting yourself". At this point I ended up lying saying that I eat a lot of sweets *which I don't anymore*. She keeps nailing into me that because of my racial background *white and african american* that I'm on the road to diabetes because of my AA heritage. I said that my father is almost 60 *he's AA* and he doesn't have it because of his healthy diet and he runs 6 days a week, but she corrected me to say "Not yet"

I started crying from her beating me down about my "future" and was so frustrated because ALL I WANTED WAS A KNEE BRACE AND ASPRIN. So prescribes these to me in the end, but also told me I need to get blood work done on my metabolic, blood sugar, thyroid and so on to see if I'm pre-diabetic. She also prescribes me a medicine that suppresses your appetite.

And after all of that, the thing that hurts me the most, the thing that I can't stop thinking about at night and that I can't stop looking at the mirror at is her last words to me, "If you keep taking this medicine, by the time Christmas rolls around, you're going to be so beautiful" And that's whats been upsetting me these past few days, that I feel like, Am I delusional?

Here are my questions that I ponder on since that visit:

Should I even pick up the prescription of the appetite suppressers if I have been doing very well so far on portion control?

When she gave me the blood work, she asked if I ate anything that day and I said "Yes, right before I went into the office, I had a small 120 cal bag of Cinnamon toast crunch w/o milk" and she said it wouldn't affect my results, but I'm afraid it's going to show that I have diabetes, when really I just ate cereal that morning. So am I suppose to fast before the blood work? Or would it have not changed my results?

Was she even right to introduce that problem to me? I know I have a weight problem, but I never check the scales just the inches *which btw, I measured after the visit, my waist is 31 and I make and commission clothing so I know how to measure* and it wasn't the purpose of my visit. I also never had knee problems while I exercised, just only for the instance. Wouldn't referring me to a nutritionist be better/healthier? *Fun Fact: She weighs almost the same as me 188, but her waist she told me was 33-34, but I can tell her legs and hips are smaller then mine which might be why I have a smaller waist*

I question her facts on health issues on races. She said that Europeans/ people from anglo background can get bigger, but still not have diabetes as much as other races and because I am half AA that I will more then likely have diabetes even when I told her it doesn't run in my family. So also claimed the health issue of Asians having high risk of diabetes because of the amount of rice in their diet, but living in Asian countries for 3 years, I beg to differ and question her facts. Should I just agree with her and say that because I'm half AA that I'm on the road to diabetes?

My last question is has anyone had these kind of experiences? Had doctors that instead of not treat you on your progress, but treat as you walk in and not listen to your story, have you had those? I'm not sure how to feel about this visit. If I should take something out of it and make it into a positive note or chalk it up as bad doctoring.

Someone please reply!! Sorry this is long, but I really needed to get this out of my chest. I thought maybe people could give me a reply on here.
