I Cant Remember Alot But This Week I've Been Getting

I cant remember alot but this week I've been getting a headache and last night at 12 I went to go wash my face but then I suddenly fainted in the bathroom and I woke up at around 1 and I barely could move. I was able to sit on the floor against the wall but I looked all blue and felt giggly . I only made it to my room 45 minutes later and I can't remember how I fell asleep but I feel better now.
