@Catatemyhomework You're not alone feeling like that, hence the necessity for this thread.
I'm late 40s, thankfully in good health so far. I have 3 dcs, teen to young adult, one with SEN. Eldest dc has already left the UK, and thriving. DH and I have a small business and we're in trouble. We were doing really well up until January. I can empathise with your worries.
