Mental Meltdown

this could be anything really. I would definitely get a blood test done asap!  most likely its probably a vitamin deficiency. Do you take a B-100 complex ?  you may not be absorbing your vitamins.  This sounds like a vitamin B1 deficiency  please follow up with your surgeon/primary care Dr and get a blood test asap!! Do not put this off , get a blood test right away... as soon as you can do it , do it! Then you will know what the problem is and you can take care of it right now! best wishes hugss Lizzy
