We can point the finger at whomever we think is to blame but really you were the one that placed yourself in the situation. Sure the docs gave you the prescription but you were the one that listened and believed that the pills would help.

Ive been in your situation, no doctor prescription though but i dabbed myself in so many pills... so many.. I would not take anything back though for they made me who i am now which is so much higher than before i started drugs and meditation.

Meditation is amazing if done right. Done wrong can be extremely dangerous as you already can see.

Be the one who is in charge of yourself/thoughts/beliefs, then the right way will show itself.
