my vision began to go black and I started to hear a high pitched ringing sound

• Cold Sweat
• Ears ringing almost deafening
• Vision Blurs before going completely black
• Nauseas
• Stiffness in body
• Pass out

I was talking to my father today when all of a sudden, my vision began to go black and I started to hear a high pitched ringing sound. Shortly after, my father said that my face was pale and I had to sit down. I could barely keep my head up or my eyes open and it felt like I was going to pass out. I held it together as best I could, but even after my vision returned and I stopped feeling like I was going to throw up/pass out I still felt like they could come back at any point.

Just wanted to know if this is something serious that maybe others have had before/checked out, or if I need to go see a doctor (I have a large fear of doctors, so avoiding them is usually what I try to do)
