Anyone else feel light headed frequently like passing out?

Ok ladies so I've been feeling horrible. I feel like I'm going to pass out. I get hot and cold and just feel like I'm about to faint and I can't breath. Any of you feeling that? I know it's weird but I feel like that sometimes if I'm using the restroom and I'm there for a while but mostly at work! Or after I eat!! It feels horrible and the only thing that makes me feel better is chewing gum and laying down! 😭😭 so weird
