I apologise in advance for a lengthy post (that might be a bit of a waffle).
I'm posting here to confirm whether I am BU in feeling useless when it has come to looking after someone with covid.
DH has been ill for 3 weeks now. It all started with the usual fevers, but he was 'fighting' through it so we just assumed he would shake it off. However, that gradually turned into awful cough, shortness of breath and so on. He has since been in the bedroom.
Initially when he was very ill, I was checking in and offering food/drink but he couldn't eat or drink much so declined saying he'd let me know if he wanted anything. I'd leave him alone for periods of time (not for hours on end), unless his cough sounded awful. I'd ask about food and drink, but not constantly because DH is the type of person who doesn't like to be constantly nagged. It then switched to him messaging me whenever he needed anything (and was easier as he could barely speak).
I've made sure if he's wanted to eat something specific I've cooked/gone out to purchase and so on.
We have two young DC, and they've been kept away (really don't want anyone else to get unwell).
Before I say why I'm here posting this, I will mention I have anxiety and it's been getting worse over these last 3 weeks.
So the point of my post is, after reading that would you agree that I've been useless, and should I have done more? Should I have been popping my head round the door every 10minutes?
I can't help but wonder if I've not really been that caring after all 
Apologies for the long waffle, I can't say this in RL as most won't understand and ILs will tell me they knew all along how useless I am anyway.
