Hope it gets better soon Kat. My mother had the same thing happen to her about 6 weeks ago. She was headed out to get the mail and basically ended up on the ground and could not get up do to the vertigo. A neighbor just happened to walk by and saw her laying on the ground and helped her back into the house. She ended up going to the hospital but they could not really find anything wrong with her other than her blood pressure was really low. Luckily she hasn't had another episode since.
