Accidentally ingested 100mg of THC edibles 😔

Don’t really have anywhere else to share for understanding. On Friday night my house mate had a friend stay over and they hung out all night cooking and whatever else. On Saturday they went to the beach and asked if I wanted to go but I am starting to write a thesis and will be busy for 3 months now and must write every weekend. When they were leaving they said there was brownies, pasta bake etc in the fridge and help myself so I did and had a brownie which from my opinion looked and tasted normal. About 30 mins later I start to feel strange and then it’s like a roller coaster to hell and back. I have never done weed as I know I am very sensitive and already get anxious. But honestly worst experience of my life and was so incredibly sick. I was on my bathroom floor covered in vomit and faeces when they got back and found me and it had been hours and I had like burns on my thighs from having faeces all over my legs. They helped me but I was in a very bad way.. I wanted to go to the hospital but they said there would be trouble when I test. Next hours I was sometimes ok and then back on the ground. Racing thoughts, paranoia, voices talking about really bad things from my past.

Well anyways now that was only stage 1 of hell. I am just completely broken now. I am so upset at my room mate, why would you not say something???? Then they said even they wouldn’t have a whole brownie and only take a bite every hour a check??? Yet I had a full one which she said was about 100mg of THC 😔 I am also mortified regarding the loss of control and the mess I was in. But now I feel like I have cracked or something and my mind and spirit is broke and irreparable. Like I’ve seen extreme darkness and went to hell.

Has anyone else had a bad experience with THC? I feel like like my life has changed since Saturday and no going back.. oh well
