Yeah idk.. if you NEED marijuana in order to even deal with life, you've allowed yourself to get into a bad spot that will have implications for the rest of your life. I don't mean to come off as merciless or compassionate, as I too have dealt with some of life's difficulties and tragedies and I can imagine the struggle/hardship that others go thru. But seriously, there are all sorts of safe, natural, and holistic ways of reducing(even eliminating) stress/anxiety or whatever it may be. People with OCD can even overcome their neurological situation by natural means and discipline. I like mary jane too, but it's totally possible to be able to cope without it. That is unless you're speaking about aliments such as cluster headaches. But if you're just meaning that life is hard/sucks then I would advise you to reconsider and contemplate the matter a little more.
