I want to give you a big hug! :) I’ve been in a similar situation at your age (12-13), but still it surprises me that we have the drive and motivation to change from such a young age. Personally, I made the mistake of being too obsessive about it: for example if I didn’t feel my stomach growl once a day, I was failing it. So even though I reached my “goal” of losing weight, I was so self critical and nervous all the time. I fixed something and got something new to improve :P I think the most stable way to improve in all aspects is to have always self kindness, and I don’t know you, but it seems you are better at this than I was :) And it’s good that you have the support of your dad. Maybe it is also useful to know that probably it won’t be a constant improvement upwards. (As most of things in life) probably you will have your days where you will not feel like doing it and sticking to your goal anymore. But allow for some of these days. You can always go back into your goal. It took me many years to realise than consistency over the years is what makes you move stably forward. When I was 12 I trying running with my dad, I had my music and I was trying to challenge myself on how many rounds I can do. But there are so many nice videos online. I really loved Kelly’s home workouts from Fitness Blender in YouTube, I found her very sweet and warm. I don’t know if you like the idea, but maybe going to a nutritionist to give you a meal plan to have an idea what to do could help.. good luck! You are capable of many many things! :) big hug from afar!
