Anxiety ?

[Missno1978]

I passed a very stressful situation but even it was resolved i still can't stop thinking about it.  I have sweaty hand and feet and canker sore on my lips and some darker spots on my foot and itchy body.

All this in less than a week.

Yes,  Anxiety is a destructive activity, which can cause a lot of physical problems.

You know what one of the biggest causes of canker sores is?  Commercial toothpaste.  It's often the sodium laurel sulfate or its cousins that cause those.  It has nothing to do, in any case, with anything else going on with you, but I just thought I'd mention that changing to a toothpaste that doesn't contain harmful ingredients might solve the canker problem.  Peace.

Interesting news for me, since I get cankers every few months. I use Sensodyne but will check out brand ingredients in others in case there are sensitive teeth alternatives that don't have SLS.

You pretty much have to go to a health food store to find them.  None of them is likely to have the type of fluoride that works so well with Sensodyne and its copycats, but there are toothpastes in the health food store that advertise as being for sensitive teeth.  But even in the health foods stores most of them still have the ingredients that cause cankers in some people, so you still have to read labels.  I have to confess, when my dentist tells me my problems are my sensitive gums, I use Sensodyne for a awhile, then return to the natural toothpaste as soon as I can.

Your negative HIV test was conclusive, so try to accept the science involved with the test and relax, since this disease has been studied for 40 years and is well established.
It is natural to sweat when you are in fear that you are dying - but you aren't. Anyone can get a canker and you probably always had the "darker spots" so it seems you are over-analyzing your body trying to find proof that you have HIV instead of accepting the scientist's test. Your doctor is the only one who can determine if the spots and itch are normal, so again it is time for you to stop self-diagnosis.
If you are unable to relax, consider therapy or discuss this HIV phobia with your doctor to try to get relief.
