Hey man, good to hear from you

.
I'm sorry to read you've been going through some tough stuff lately, but I applaud you for speaking about it and trying to do something in the wake of your problems and you should be proud of yourself for valuing your body enough, in light of your problems, to want to make change
This is the sort of thing I post for people sometimes and you might find it useful.
Breakfast
Option 1.
Bowl of Whole-grain Cereal and 1 rasher of Bacon, fat trimmed off and scrambled Eggs, (2 Egg Whites + Yolk)

You could add a few things to certain meals, like Sea Salt, Cracked Black Pepper, Parsley, Mustard, Herbs, Garlic.
As for the training you could do a schedule something like this, which is all bodyweighted.
Squats, 2 sets, 10 reps
Lunges, 2 sets, 10 reps
Good Mornings, 2 sets, 10 reps
Bent over Rows, 2 sets, 10 reps
Pull-ups, 2 sets, 10 reps
Shrugs, 2 sets, 10 reps
Planks 30 seconds.
In relation to the training ideas I gave you above, your bodyweight workouts and cardio schedule could look something like this.
Day 1. Bodyweight
Day 2. Cardio
Day 3. Bodyweight
Day 4. Day off
Day 5. Cardio
Day 6. Bodyweight
Day 7. Day off.
This prevents you doing 5 days straight and 2 days of nothing, as I think that's allowing too much consecutive taxation and 2 days of your body doing nothing, slowly starting to adjust to it, before 5 days of grind again, which might take the edge off progress potential, so the 5 split days should be better for you.
