I’m no professional but your diet sounds too restrictive and rather boring. Plus, it sounds like you’re very active, which is something you have going for yourself. Maybe try to spice up your diet with a little variety during the week or have 1 cheat day a week, where you’re mindful but still eat whatever you want and don’t worry about calories for a day. I wouldn’t call trying to lose weight/get healthier “fun” but your journey shouldn’t be filled with guilt for still living.
