You seemed to of found a crutch. Dont blame cannabis for your lack of motivation. Blame yourself. Cannabis is probably the last thing that unmotivates a person. Cannabis does however have the ability to expose those things that you are doing that really arent worthwhile.
Dont point to things that will get you the most sympathy for your fuck-ups.
If i were a prohibitionist i would print your story on all anti-cannabis websites. What a courageous person you are for finally admitting that cannabis is fucking up your life. gee whiz and wowie. fucking loser.
You get no sympathy from me.
