Digestion complications after COVID

I had covid in May it was pretty bad, but was able to isolate. I have had symptoms come back and some days I have been fine, but for the past month I have experiences with Severe Constipation, being Shaky, dizziness, migraine headaches, loss of appetite and vomiting, but no fevers. I have been so distorted I can't go in to work or drive. I can't even clean my home without feeling as though I am going to faint. I have tried using laxatives, but they don't work. I am now dealing with fecal impactions
