So sorry for your losses Unicorns 
I hope you're starting to heal from your surgery, I had an MVA after my MMC.
I've had 4 MCs, one was many years ago, so 3 in the last 18 months or so, and no DC yet. I really feel your pain, it sucks beyond belief and I know what you mean about having little left in the tank.
Everyone deals with things differently but things which help - knowing the grief will come and go so enjoy the days you feel alright and be gentle with yourself when it hits you, appreciate your body even if you feel it's let you down so eating well, exercising if you enjoy that, really looking after yourself, keeping busy if distractions help, remembering you had a good life before starting ttc so don't let it take over completely and keep the rest of your life and relationships full and nourished.
The single most helpful thing for me is chatting to people who really truly get it, these women on here are strong, brave, hilarious, kind, patient, supportive, and keep each other going on the bad days and celebrate on the good days.
You're very welcome here, I hope you get a BFP soon and can move on if you want to but stay as long as you like, you're among friends.
