Do I appeal ?

Hi Up until my pip review at the end of last year I received standard pip care (11 points ) And standard care ( 8 points . Four for guidance and four for walking ). I suffer with spinal osteoarthritis and severe anxiety and depression. Result in renewal was no change in points totals but I lost the four points for needing guidance but was given eight for walking. I asked for a MR and gained an extra point for my back care needs. No change in mobility. But now enhanced for care which was pleasing. However, I was annoyed to have lost the four points for guidance which had previously been awarded at a tribunal. I can see that a gap in my evidence may have lead to this. Given my mental health problems I like the rest of us could well do without going to tribunal. Should I accept and be grateful for what I have or should I try and get the four points back at a tribunal ? Grateful for any thoughts.
