I took LSD once and I went crazy on it.
Why would you take LSD? Did the experience turn out poorly for you?
I ended up running into a wall and hurting my nose.
When someone uses drugs they are putting themselves in danger, any time a drug is taken there's the potential to put your life at risk. It's better to just not take drugs at all instead.
I was only trying to have fun.
I understand that trying to have fun, but if you need drugs to have fun there may be some problems. If you are not happy with a sober lifestyle I recommend talking to a therapist or finding hobbies to keep your mind occupied.
