Don’t be too hard on yourself. It’s harder to quit cigarettes than quit heroin. Add dealing with a severe mental illness on top of that. Maybe talk to your pdoc about it. They may be able to help you quit.
Was going to post what I smoke. But mainly One I couldn’t find any pictures of roll your own tobacco on the net. Two It’s lilble to be taken off with the graphic images of things like lungs with emphysema. Toes with gangrene caused by smoking etc etc. Some may find it disturbing so thought better of it. Anyway they look all the same here in oz with the very lovely army green plain packing and a few graphic images.
