I think I passed out for a second?

I think I passed out for a second? I was feeling like, super tired all day, and that's not abnormal for my days off. But I also just felt super out of it I guess. Anyway, I didn't eat too much (a poptart and a granola bar) and at one point I got up I guess it was a little too fast? I only vaguely remember leaving my room. I do remember entering the bathroom and calling out a greeting to my mom. Next thing I know, my vision is all blury, I'm on the floor and my legs are shaking strangely. I hear my mom say "that was weird" and I don't remember leaving my room. After a moment, my vision comes back, and I then I remember entering the bathroom. I apperently still don't remember my step dad asking me if I'm okay from the other room. I'm still shaky and I went to eat something and drink some water. Also. there's now a hole in the wall where I fell. I probably wouldn't have even told anyone what happened if I hadn't had to explain that...
