I hope...

I hope this is just some kind of stress side effect or from working out... I hope that there's nothing [else] wrong with me... I hope I know what to do if there is...
I've been somewhat of a hypochondriac for more than awhile and it's kicking in big time right now. Lately my shoulders have been bothering me, like I can't rest/sleep on one side for very long or my arms get weak or tingly or fall asleep. But now, like as I'm writing this, my shoulders feel tired. Could it be from poor circulation? Because I know I have poor circulation, my hands are always cold. Maybe I'm overreacting - anticipating some diabetes complication to kick in. Like my eye sight has changed... again and I have an astigmatism. Is is because I have diabetes or is it just a natural thing that happens? Aging and whatnot? I also just noticed I have red marks on my pinkies... After eight years of this I hadn't really thought about complications, just recently have I begun to contemplate the future, my life in 8, 18 or even 38 years from now... it freaks me out to think of these things. It is, however, a reality of living with diabetes.
What's next? ...
