Hi purple Sinatra, welcome to PC. I am sorry to hear you have been so challenged. Being exposed on a daily basis to someone who is "toxic and can be abusive" for a long time can do more harm to us then we realize. Research has shown that people who are bullied in the work place can develop PTSD.

There can be headaches that happen with PTSD, I struggled with that myself. My headaches made me feel like my brain was being squeezed, and completely tired me out. I also have felt the headaches in the front of my brain too. I have been told that is a tension headache, but I am not so sure that is true.

Have you tried any medications that help with anxiety? If so have they helped with the headaches?

Also, I don't know if you are male or female. If you are female, hormones can have a lot to do with headaches. It could be connected to your hormone cycles and that is something you should consider.
