Tomorrow starts the beginning of my self improvement and I'm excited

Long story short I'm going through it and am struggling to find a reason to keep going but I've decided that now that I have the ability to focus solely on myself then I would be stupid not to, why give up? Why let your sadness drag you down? Show her the best version of yourself and if she can match that then try again if not then say goodbye but stop focusing on what you've lost, stop looking at the good times as though they were so special because while yes they were you were also mistreated, you deserve better you deserve more from a potential partner, you deserve better of yourself. No more soda. No more sugar for at least 2 months. No more pizza or junk food. Light workouts before bed. Light workouts before work. Going to the gym at least 5 days a week (mostly cardio) and pushing passed your tiredness don't give into putting it off. Get off your ass go for a walk instead of sitting at home. Find nearby groups and put effort into making friends. Save up for a new car and bigger place, in a few months adopt a dog and eventually everything you want will be yours or right there within reach. You've got this man. 'Yes I do' is what I told myself.
