Bad trip from an unknown legal smoke.. Will I be ok?

Hello, it's currently 12:33 AM. Around 8pm my cousin who lives with my grandparents convinced me, through severe pressuring and "come on, come on" until I no longer refused, to smoke something he told me would "make me feel good". I've smoked other stuff he told me to before which only left me a little relaxed or tired, didn't mess with my brain really. He failed to tell me it would have some kind of trip effect... I cleared a pretty large "sour" bong of the stuff and held it in for a pretty long time each hit. A few minutes after hitting I was sitting down and started feeling really weird, then time started being all trippy, like stuff was replaying/lagging. It started off being only every like second time would mess up. I stumbled into the hallway and tried to go down the stairs to get help, but I fell down the stairs. Around this time it started getting worse, time started replaying more like every few minutes. I was totally out of touch with reality. Then I totally went out and saw like little multicolored squares on a black background and while in that strange dreamlike state I forgot pretty much my whole life, random things flashed back and forth in my memory... Then I like saw weird color swirls and little like rocky looking vortex things, it felt like i was being drug/swirled through them and the physical pain felt real. Anyway, eventually it slowed down, time got back to messing up like every 10-30 seconds, I felt a strange tingling sensation all over, couldnt get up, and threw up about 10 times, at some points very violently to where I had a spasm like thing and slid up the back of the couch. Eventually the tingly feeling went away and I was still throwing up a little. I tried eating small stuff and sipping some water and sprite but threw it up most of the time. My grandparents tried to help me and did take care of me until I was back to reality and calmed down. I am at home now and I feel kind of bad like worn out, kind of sick stomach. I am done using any kind of drugs not prescribed to me by a doctor. My advice to anyone is don't smoke anything, and if you're going to make sure you know what it does. My stupid mistake, I learned a lesson. Anyway, I'm thinking about going to sleep soon. Do you think I will be ok? All I know is it was some kind of incense and the initial trip lasted a little over an hour but the whole bad experience was more like 2-3 hours. Please answer I'm a little worried. I'm just glad that is all over. By the way, I'm not "tripping" anymore the time thing stopped before the tingling sensations, I just feel kind of sick/weak/dizzy. Thanks!
