I need help with my bills how should I go about it?

Hey all, this post is a bit embarrassing for me to even come and ask, I've been unable to work due to chronic pain caused by an unnecessary emergency surgery last year and honestly it's messed me up. I'm 2 months behind on my gas and electric bills and I'm not sure what to do. I can't ask my family for help as they're not well off and I don't want to be a burden.

Someone suggested setting up a gofundme page to see if strangers might be able to help but I feel like a complete failure not too myself but for my children. I'm £318 in debt and I'm trying to make up for it but now they're moving it to debt collectors and I'm freaking out.. I'm not asking for money, I just genuinely need advice on what I can do.. would a gofundme even be worth it? I'm trying to sell things to make up for the money and even making crochet items to sell but I'm not getting any buyers at the moment and the money is due tomorrow and I've just given myself no way out. I've never had problems with bills I've always paid them on time, just these last 2 months have been so difficult with school payments etc.

Any advice?
