I don't know where to post this but this problem is stressing me out. Since the past week I've been feeling sick and light headed which results in me breathing heavily. I don't even feel like eating; and if I do it makes me feel sick at times. It is affecting my everyday routine, I cannot even sit still as I just have to get up and walk out for some fresh air. It just happens randomly anytime during the day. I thought I got better as it didn't happen for 2 days, then it decided to kick in again! And also, my sleeping pattern has been a bit messed up recently too. I don't think I'm getting enough sleep although I go to bed early. The other day I went to bed at 10, could not sleep until 4.30am, woke up again at 6am and after that I just couldn't get back to sleep... But still even if I don't get enough sleep I still feel fresh. I don't know what to do.
