Ah the emotional journey of not being able to get over someone and all that drama of on and offs, I have been in that place and it is tough on the heart, it makes it harder to trust people again in that romantic way.
Military training? Well that must have been hard.
I think it is a great idea to start with walking. I also have a tracking app and I have a daily minimum goal of 10000 steps. It does help to set small, reachable goals and progress from there. Swimming is awesome for losing weight and not feeling the effort as much as if you would run.
Audible does advertise a lot, I did not give in yet lol. I listen to Eckhart Tolle's podcast https://podcasts.apple.com/us/podcast/eckhart-tolle-essential-teachings/id1458654443

When I walk in nature I listen to nothing, I just walk in silence.
Just be gentle with yourself and give yourself time. Also drink lots of water. I don't know how your metabolism is working, but since I became a vegetarian I managed to lose weight and feel better. Eliminating junk food is huge and slowly I think that you will succeed, the ambition and drive is there! May the Force be with ya
As for good food, it helps to eat veggies and fibers and high quality protein. Avocado is so good you can eat it daily in your salads. It helps to stop eating after 6 pm, unless you plan to have a walk / or something better people prefer to do at night lol and lose those calories. Some people get a nutritionist to help them with a schedule, I think it depends. Ah don't get me started with healthy foods I will write a fat reply lol.
I remember when in one summer I gained some extra weight because I would not eat during the day and stuff myself at night with junk food. One day there were several clients who asked me, smiling with joy : Mary , do you want to tell me something, I see you a bit different...are you pregnant?LOL.LOL. My face dropped, so did theirs. Because the only thing I could have been pregnant with was the undigested junk food from the previous night and the extra fluffinessš¤£š¤£. That day I was commited to change. Like...come on...several clients telling me the same thing. It was annoying for my ego. Plus I already have a chubby face with dimples, no bueno for me to gain weight. At least nobody will ever ask a man about pregnancy in case of abdominal fat hahah.
I hope my reply helps in some way
