Earthquake experience, help!

I experienced an earthquake like a year ago. I was sitting on my bed and I heard a sound, it was like a really strong wind. Then the bed started shaking. Walls were like pixels. I tried to stand up but I couldn’t my legs they weren’t working... The chandelier was making a disturbing sound. I was so scared. Then the lights went out. Then it ended. I think it lasted about 20 seconds but to me it was a lifetime. I can’t stop thinking about this. When I’m in bed i remember this and I can’t sleep. When I heard a sound like that or feel a vibration i get so scared. I’m shaking even now. I feel so bad please help me. Feel better.
