Oh boy. Pot can actually be very helpful in helping to manage anxiety symptoms. For a person who is too anxious to relax or fall asleep it can be very soothing. And of course as we know, really doesn't harm your body, whereas alcohol is horribly harmful to your body. There is a big difference, though, in smoking to reduce some symptoms of anxiety and smoking so much that you're missing work and not following through on other responsibilities. It sounds like it's causing you to be super unmotivated, and you don't seem to be happy about that. So you need to think about how important (or not important) it is for you to get shit done and whether you're ready to maybe cut back a bit. It can be really helpful to ask yourself what you were thinking about right before you thought, "I wanna go home and smoke," because those thoughts are what's causing the anxiety that leads you to smoke.
