Maybe there’s some depression you’re dealing with. A lot of this is characteristic of ADHD, just a thought not saying you have it and it can be over diagnosed. With that being said, I am in that same struggle in varying degrees with myself alllll the time. I set plans that I have to show up for - so things like going to the gym- I go with a friend that I don’t want to let down. Orange theory charges you if you don’t show up. Book tickets to an event and just get it without thinking about your schedule. Once it’s on the calendar it tends to happen. Sometimes a vitamin B12 shot gives me that extra boost when I’m in a slump. Leave your smoke at a trusted friends house and be just uncomfortable with knowing it’s not at your fingertips.
