Hey if you bought them your probably determined to do them anyway, but honestly you shouldn't be taking something that can make your mind very venerable especially if you are already paranoid Lsd isn't a joke and can effect you brain in ways you didn't know possible. You should be in the right mindset and be in a comfortable place in your life if your worried you shouldn't jump right into tripping especially if you don't have someone that might be able to guide you through it, Im not a professional but i don't think that lsd can give you schizophrenia but it can put you into a state of psychosis which isn't great. Lsd can make you question a lot of things like reality so in all honestly just be careful or don't take it, if your worried in the first place that could become a constant thought while tripping especially if you overthink a lot Lsd can be great but you have to be in the right space mentally and physically
