I would like a brain scan as I've never had one and my anxiety comes up at times I'm not even stressed. Today as soon as I got out of bed my anxiety reached the maximum level and I was trembling, heart racing and making me very uncomfortable. I've only had check-up's with regards to my bloods, my eyes, my lungs/breathing etc. The main issue for me is my brain, it's doing things that I'm no longer sure is just a cause of mental illness, I feel like I honestly have a brain tumor or I'm simply going insane.
Three years ago I was never like this, I never had anxiety, never heard of anxiety and once I started and stopped taking prescription medications for depression and my sleep, I began getting anxiety and now that I only take 7.5 mg of Mirtazapine (been taking it for almost a year now) I feel like there's no reason for me to have this intense level of anxiety. It will happen like a trigger in my brain, I could be having a really good time, laughing with friends or family, then suddenly it's like someone pulls the trigger of an anxiety-gun and I stop smiling/laughing immediately and feel so weird within my body. I'm always waiting to faint or just collapse and die but it never comes. It's like an intense build-up to something like a seizure that never comes. Also, I get nasty headaches on and off that sometimes aren't helped with pain killers.
So, for the peace of my mind I would like a scan on my brain. But how do I go about getting one? I'm in the UK and I can't see my GP referring me for one.
