Weird symptoms

I am getting a weird kind of migraine, First, for two and a half years it was a nagging twinge on the right side over my eye. Never an intense pain or a big headache, but lots of other weird and creepy things with it. Felt sick, felt exhausted, felt like crying, sometimes my legs wouldn't work for five minutes and I had to just go down onto the floor.
I woke with my jaw clamping down hard inside my bottom lip, and it even drew blood sometimes. And my neck felt unstable, like my head kept wanting to turn a bit to the left.
The worst thing was the exhaustion.

But now it's all changed and for the last month or two my ears feel clogged. When I talk there's a strange sound like I'm talking inside a box. I start shaking all over, get so scared and anxious and don't really know why. The scared feeling isn't from bad thoughts, just a part of the symptoms.
Then I'm lightheaded and get lots of heart palpitations. Slow and fast heartbeat. One night it was 48 beats a minute, then the next day it was 100 resting. My head feels like it's being blown up from pressure inside. And there's ringing in my ears. I feel like I am coming down with flu almost every day.
I can't enjoy my food any more. I always enjoyed my food. I often feel steadier if I eat, but there is no pleasure and just anxiety when eating.
I just cry. It sounds mad but it's the only comfort I can find.

Sometimes when it comes on before bed, I can't sleep until 4 or 5am. Feel too scared to sleep. Even the tiniest bit of stress, like someone saying they are going to visit and I have to figure out what to cook for them triggers the symptoms, or if it's a grey day.
Yet 99% of the time now there is hardly a headache, or maybe just some mild twinges. But the other symptoms make me feel I haven't long left for this world sometimes. I am so terribly exhausted every single day.
I use to walk miles, but now can only manage a very short walk because of the dreadful exhaustion.
