Weight loss challenges!

So I was on a forum for weight loss (I won't mention where) and I was summarily criticized for the following:

1) Not eating leafy green rabbit food
2) drinking WAY TOO MUCH soda (2 cans a day at best nowadays)
3) Drinking (even though I explicitly said I don't drink often)
4) Eating any sweets of any kind (which really I don't, not anymore)

WTF is wrong with people?  They're making assumptions that aren't true, and what's worse is when I say I can't eat certain foods, they assume I haven't tried.  Let me tell ya something.

I HAVE TRIED!!

I've tried so many times in my life, and have gotten the same result that after a time, I no longer wanted to try knowing the result all too well.  So what makes people assume certain ideas that aren't even verified?

First off, I once was drinking 24 cans of soda a day.  This can be vouched for by one of my friends for certain.  I'm now down to 2 a day, and sometimes I don't even have that much.  I'm starting to drink gatorade and incorporating water into my diet.

Second, some folks assume that I drink regularly.  I don't.  I drink maybe once every few months, but sometime several months can go by and I don't drink beer at all.  Nor do I drink wine, spirits, liquor etc.  Because I take medication, I can't drink anyway.

Lastly, the sweets.  I rarely eat sweets anymore because I don't have any teeth to eat sweets with.

I'm done going to sites about weight loss, because some people just totally suck when it comes to taking my circumstances into consideration.  At least my effing doctor listens and understands.
