Ringing in ears and then seizure

Hi there, I’m trying to figure out what’s going on with me? I’ve had a lot of ringing in the ears, and I thought it was related to blood pressure. But my blood pressure is fine. The other day I was sitting having coffee with my husband, and I was experiencing ringing in the ears so loud as I was discussing something that was stressing me out. Then my husband said all of a sudden I just stopped moving, my head went forward my eyes drooped, and I couldn’t move my body, I couldn’t talk, but I was cognitive of everything around me. My husband said he tried to get me out of it, but I couldn’t do anything. It lasted for about 15 minutes, I was reading fine, shallow breathing, but I focus on my breath so as not to freak out. To be honest I don’t think I could’ve freaked out because I was kind of very distant from everything around me. My husband ended up calling the ambulance, but by the time they got here I was almost back to normal. I went to the emergency room, And of course they had no idea what went on, and even doubted that I was correct in my narrative. They did the basic testing of vitals, and I urge them to refer me to a neurologist. I am currently waiting for a appointment with a neurologist and hopefully will get an MRI. I don’t even know if this is going to show anything. But what I do notice is if I start talking about work and getting stressed ,My ears start ringing louder and louder, to the point it becomes deafening and I start having small deattachment/ seizures, or at least that’s what I’m calling them. I am worried nobody’s going to believe me, and they’re not going to figure out what it is. Does anybody have any idea or have heard of what I am going through? So right now I’m just trying to be per cautious, and just try not to get upset, because I’m scared it will happen again. I’ve had a few short ones, where I get slightly dizzy and then I need to sit down and then I’m just out of it for about a minute or two.
