Hi! For a little over a year now, I've been getting lightheaded (a few times to the point of briefly fainting) every time I stand up; the dizziness is always accompanied by seeing light spots (like when you stare at something bright then see that shape for a little). For the past 4-5 days, I've had a constant mild headache, much worse disorientation/lightheadedness when standing (even though I'm getting up slower), and last night I first experienced pressure in my head when I tried to lay down. I fell asleep sitting up with pillows to my side because i can barely decline my body without feeling that head rush and need to sit up immediately. I have very bad anxiety, and this is making it so so much worse ): thank you for reading and please don't hesitate to share your opinions!
