Fainting and trouble sleeping

Christabel

Is anyone experiencing this? Im fainting around three times a week. I start to see black, my legs get all wobbly where i have to lie down, i get sweaty, my breathing gets shallow and my skin turns pale white. To top it off i cannot seem to sleep more than a couple of hours each day. I get startled and awake everytime i drift off to sleep and when i do manage to sleep, it is only for around 20-30 minutes before im awake again. Please help
