I need some life advice...

I am nearing about 6 years of having headaches every single day. I have tried surgery, CT scans, MRIs, plenty of meds, plenty of lab work, etc... and I still cannot get rid of my brain fog and headaches. If I am being completely honest I am in a dark place right now, I don't know how much longer I can take this. Anyone got advice or a related experience? I have simply just become miserable, sour to others, and lost all motivation. I used to be able to deal with it and put on a smile, but I just feel hopeless now.
