Should I See A DR?

I only ask because I don't have insurance, and I don't want to go unless you all think this sounds just like you.

Anyways, I'm 24 years old, and last year my husband said something about how I am just like his boss (who has diabetes ), and i brushed it off. Fast forward to the present. I am constantly battling athletes foot, I just found a patch of skin on my back that has gone numb, I get urinary tract infections more often then I assume is normal. I am already a pretty thin person, I had to have my teeth removed 2 years ago, (my teeth, despite brushing and flossing, rotted from the inside out, they couldn't save them) and i lost a lot of weight then, I was at 135, and I am at about 115 now. I assumed it was from the oral surgery, but it's still happening, and I eat regularly. I don't have the healthiest diet, I do drink a lot of cola and sweets, which is why I figured I can't be diabetic, cause all the sugar would have killed me by now, but I was told there is more then one kind of diabetes.

So anywho, I am getting a little scared, as I start to show more and more of the symptoms. I am not usually the person to go online and look this kind of thing up, so I am a little freaked out now.

Also, I have always had cold hands and feet, almost tingly. For as long as I can remember.

Does any of this come up as alarming or crucial? Any comments welcome. Thank you.
