It does sound as if you have much to cope with. And not getting enough sleep is probably not helping you.
They say a trouble shared is a trouble halved, or something like that..so hopefully messages here are a help to you. Sorry but I can't help with hay fever advice or how to cope with your foster child; but hoarding perhaps.
DH is so reluctant to get rid of stuff years old, (better keep it ,just in case he says). My strategy: Give him small pile to sort himself. If it doesn't get done after a few days I suggest would he like me to do it; I go through it (in case there are important legal documents) then after a couple of days suggest there's nothing really needed from pile. Stuff then gets 'filed' in the rubbish bin. He's happy, I'm happy. It works for paper, old clothes etc. Yes, I know you're having to do it in the end, but little and often isn't quite so stressful as piles of junk and old boxes.
Good luck and stay strong!
