worst enemy

I told someone that I know the otherday that I would not wish MS on my worst enemy, he has been having some numbness lately and thinks it could be MS or a pinched nerve.  I told him not to assume the worst and see a doctor.  I know that things could be worse for me, but I am still not happy about things.  I think and I've heard that things are going to get better for my health, but they haven't yet.  I MUST STAY POSITIVE.
