what you likely have is called metabolic syndrome, or syndrome x- called syndrome because the conditions you list are interrelated- one leads to another, another makes one worse, etc.  Best you can do is lose weight to alleviate the symptoms.  The cause of metabolic syndrome is likely genetic, and brought on by years of belly fat/overweight.  As to the specifics:

SA- no- can be caused by obesity, which can suppress the airway

ED- yes- DM damages circulation to penis

CKD- yes- DM damages circulation to kidney

anemia- no- can be caused by CKD (kidneys stimulate blood cell synthesis, so bad kidney = low blood count)

pain in arms and legs- yes- DM damages nerves

SOB- no- make sure you don't have congestive heart failure, or fluid overload (check for wtaer on ankles)

dizzy- yes, but only with blood sugar swings- more likely cause may be blood pressure

Metabolic syndrome is quite common- you're not alone!  My advice is to join a weight loss/diabetes support group- most of these symptoms can improve with weight loss- staying on top of it will lead to a healthier lifestyle.  Good Luck and remember- the reason it's called syndrome x is that nobody knows what causes it!
