I have been waking up lately for the past month or so feeling quite lightheaded and dizzy , it seems to wear off after about 40mins after getting out of bed. But recently things seem to get worse, as I feel I have little control over my senses, like I start feeling more faintish and this morning in particular I had problems breathing, like my lungs were closing up, vision very blurry, tingly sensation on my skin...so I had to lie down for 10mins before I felt normal again. I am only 20yrs old, I have had no health problems my whole life so far...any ideas?
