I spent most of my twenties and thirties depressed. Eventually I worked my way through it and for some reason got over it. But I can unequivocally tell people magic mushrooms are not the answer.
Having engaged in shrooms in my early days I can tell you that that stuff is very hard on your body. If you want to ingest a drug that makes you sick to your stomach for the first 30 minutes or so then if you can keep yourself from throwing up leads to hallucinations and uncontrollable laughter for about 4-5 hours followed by feeling like krap the next day then knock yourself out.
A 25 year old body can deal with anything but if you are the average over forty American do not try this stuff. It is not good for you.

Try to keep an open mind.
