Does anyone have low folic acid?

Does anyone have low folic acid. Been tired for years but this revelation came up after a blood test which hadnt been done for over 10 years

i have just found out that my folic acid is barley registering and i dont drink i take multi vitamins every morning plus i eat fruits and vegetables. i have felt horrible the last few months no energy passing out and basically every symptom there is. im having more blood work done tomorrow, should i be more scared than i am
