Anxiety and some depression

hey everyone, so the last 1 and half weeks iv been off work ill with a bad virus and still a chest infection.. I am alot better then when I was but still have moments of feeling crap!! but since being of work yea iv walked the dog an done some stuff around the house but I'm finding it hard to go out again even with just family or my partner like il do it but I would feel proper anxious like I'm going back to work soonish but even the thought of it is making me feel anxious an before I was ill I didnt really feel anxious while working.. I duno if it's down to me being ill an having the time off but I hate when I get like this I feel like I take 5 steps forward an 10 steps back.. does anyone else eva feel like this when ill?
