may i ask how you sleep at night?we should fall into a deep regenerative sleep ,ideally you wouldn't wake up at night,no even at 2,3or 4 to go to the loo...
Sleep detoxifies cortisol-stress hormone but you mentioned your legs are swollen-could you be producing too much oestrogen?is your diet "clean",been enough?do you have enough fibre in your diet?
also have you tried taking supplements?Magnesium is amazing!also fish oil and a probiotic!
I'm also wondering if you have a food allergy?if you do,find out what can that be?do an elimination diet,then slowly reintroduce each thing at the time and pin down if it's dairy,gluten,nuts etc that makes you unwell and stop eating that thing.
I don't think Converse make you get swollen legs,there more to that.
I would love to hear more about how you feel and see if I can help
