I've just been told today after around 2+ years of feeling drained,tired,fatigued,mardy,depressed and just plain down that my B12 levels are low apparently called folate? I now have to wait a month to see a nurse to discuss my diet although it's not that bad, I have bought some folic acid after talking with a chemist in the hope this will help in the short term while I await my appointment and continue to feel terrible. Am I doing the right thing by taking these tablets? Am I on the correct page for answers? And will this get better? Please say yes I can't keep going like this.
