Every day is a new day. I too am brittle diabetic type 1 and tend to put others before myself, which is rather silly really. Think of it. If you take time, even a few minutes a day to take care of yourself (I am speaking to myself here too!) and make sure that you are within normal ranges, neither too high or too low, then you would be far more likely to be more effective in what you are doing! Likewise, if you are anaemic, it is a sign that it is time to make the effort to work out what is going on, and treat it and get better in many ways.
I was extremely anaemic, feeling weak, dizzy, cold, breathless for quite some time until I was taken into hospital with a cyst on my pancreas and another on my spleen. When they did an endoscope to find out more, they discovered several bleeding stomach ulcers. I was given medication for these, had the spelic cyst removed and several blood transfusions and I felt soooo much better! Unfortunately they had not checked for diabetes until just before I was due to leave the hospital - and ended up staying two weeks longer! Once everything was dealt with I was far more energetic and clear in my mind and body. I was like a new woman!
I say go for it! You owe it to yourself, to your colleagues and your family!
