It's not the solution to depression. Don't keep going, take some benzos or something, your walking your way into a psychosis if your vulnerable enough to it. I've been where you are now, using 3-4 days a week, starting to have bigger & bigger binges. I remember the aching body, my eyes vibrating back open when I would try to lay down & close my eyes & want nothing more than to be asleep to escape my increasingly frightening mind. I watched a few friends lose everything. I live in Aus too, ice is such a curse here.
