you should try and stop using bleach
it not only damages your skin
but also produces chloride, which mixes with water to form HCl
so you are basically using acid to bath.
diabetes if well controlled, usually does not cause any problem
of course the complications of diabetes may develop
few examples of which are
retinopathy, neuropathy, nephropathy etc
but they develop in everyone
vitamin D deficiency is finding a supportive role in lots of diseases
but it can be corrected quite easily
easy replacement therapies are widely available
hope that helps
best of luck
