You are a young man and seem to genuinely appreciate the nature of psychedelics and their profound effects...

I have to be honest though.  I do not think you are looking in the right places for answers to your depression.  I cannot recommend that you start dosing on powerful hallucinogenic drugs with the self proclaimed problems that you've had with depression. 

IMO psychedelics will consistently produce heightened levels of depression at this stage in your life.  I think that you need to start looking into what is causing the depression and try to get to the bottom of that issue before you start delving into these types of substances.

I mean no disrespect to you brother, and i truly appreciate your intellect and inquiry.  I just have to be honest.... as much as i love and appreciate hallucinogens, i cannot recommend them to teenagers with emotional distress and high anxiety!!

Regardless, I hope you have safe travels brother!  Keep your head up man.  You should be enjoying highschool while you can!  Trust me... you are going to look back one day and wish you could go back to that level of carelessness! haha.  I know i do!
