If you went to a mental institution then I would recommend not smoking again, mainly because my aunt went through the same thing, she used to smoke a normal amount probably an 1/8th every 2 weeks and did shit like acid once and shrooms a couple of times and she was fine, but then she had stressful problems with her parents getting divorced and her dad putting pressure on her to go against her mum, and then this led to her being stressed on top of this she smoked a lot as well to try and clear her anxiety, this only made things worse until 2 months later she was diagnosed with cannabis psychosis, apparently a mild type of schizophrenia and now she doesn't touch weed although she loved it. I've seen her many times since this and shes doing amazingly, shes an amazing artist, musician and a great aunt , b t w she's only 24, I know shes very young but these things are worse the younger you are, my advice is don't smoke anymore or in the tiniest amounts, e.g. half a gram every 2 weeks over the space of 3 hours, it's long but at least its better than being sober.
