I've been having weird feelings. When im at school in a classroom just sitting down, It will feel as if the room is moving. Not spinning, but just like my equilibrium is off? Another example of this, is when im driving, and then come to a stop, it feels as if im still moving, when im completely stopped. This has been getting to me lately and its happening more and more often. I get sick to my stomach when this happens and I feel almost as if im going to throw up. Is this due to stress? I talked to my doctor and he seemed kinda baffled and was clueless.. Any help?
