I was doing quite well for the last couple of weeks - I'd been fairly successful in telling myself my headaches were down to anxiety and neck tension, although I still thought about them ALL THE TIME. But last night I had a split-second moment of dizziness and I freaked out. I couldn't sleep, I've been panicking most of today, and I've been crying for the last hour because I don't think I can do this any more. I keep thinking my headaches are a brain tumour and that I'm going to faint and hurt myself. I tried to challenge my thoughts but I couldn't do it. I don't think I am going to get better and I can't go on like this. For medication I am on 50mg Zoloft a day and it's not helping me.
