Over the last 2 years have had an increase in weight and mood swings with little tolerance to stress. often tired. exercise 2 weekly. i had the mirena inserted 2 years ago and apart from having some bleeding afterwards, have not had my period since?

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health!

Clean up diet: One place to begin might be avoid inflammatory foods which cause many people symptoms such as you describe -sugar, grains and dairy are the most common culprits , focus on getting healthy fats, health proteins and lots to green leafy vegetable, regular exercise (30 min walking ) can be very helpful as well.
