How to keep yourself away from the dizziness from smoking the pot?

I smoked pot yesterday and immediately I started seeing thick vertical lines moving in anti- clockwise direction. I tried to act normal in front of my friends. I just said " Its time for me to go home" and left. I walked alone and then I could see two different things with my two eyes. From my left eyes I could see the pain and hardwork of my parents while from right eye I could see the enjoyment and sex and bla bla bla. I came home walking through hard struggle. I sometimes felt very pain in my head and sometimes so relaxed. I tried to sleep for very long time. And today as I woke up, I am feeling everything strange. I just went to work and came here. Whenever I try to concentrate, I couldn't? I haven't eaten anything from yesterday. Please help me. I am not feeling any pain but my body is so lazy now. I sometimes feel like I am going to die. Please help me. I dont believe in GOD. Is that the problem?
