Help 
I need stories from people who have experienced being a single parent to two young children with zero childcare options.
I'm do not believe I'm so unwell that I need medical attention, and I'm not looking for medical advice, just some friendly anecdotes from anybody else who's had to pick themselves up when they physically don't feel like they can any more. It's different to when I used to work. If I collapse on the way to work, most of everything would have remained fine.
I've changed my username because I live in sheltered accommodation. That's relevant because dad watching them isn't an option and I'm not allowed to have visitors here. I don't feel well enough to drive them all the way to my mum's to ask for respite, and also I'm not interested in making her unwell. Children are 3. I used to be a regular poster here and I don't have a troublesome history (I hope).
Does anyone have any reassuring tales, or memories of feeling the same? Where are you now?
