On saturday i woke up with the impression of missing oxygen and after the lunch i started to feel out of breath and dizzy and to have heart palpitations. Then i felt tired allday long and stayed in my bed. on sunday i didn't move too much and stayed in my bed feeling tired and wanting to sleep. Same thing today. in general i don't sleep well but this is the very first time it happens to me. usually i don't feel the need to sleep so much. by the way i am 19
