Bear,
Been having some similar issues and was put in hospital for 4 days for sinus infection I thought had basically gone away...but hadn't...please do go get checked out by doc or urgent care and get at least some sinus X Rays..so much funk in the air right now. really hope you feel better soon. It is so hard when you are already depressed to go get help medically too or to differentiate between which is making you so tired...
Gentle hugs..
wys
