You want to be healthier? Then you have to start making better choices for yourself.
You want to run faster? Then you have to start doing the strength training and interval work.
You want to lose weight? Then you have to start being more aware of the food you chose to put in your body.
To change your current state, then you need to start reflecting the person you want to be.
To be the person you want to be, it will mean adopting new habits - scheduling four workouts per week, taking the time to meal prep, going to bed earlier, etc.
But it will also require you to eliminate your triggers. You will never win the war by running away from the battles.
This might mean you have to burn some bridges - your unhealthy habits, negative mindsets, draining relationships, harmful attachments to the past, you name it! You need to ditch what does not serve you and your dreams.
