Need help, not sure what to do

I posted the other day about my husband with depression. Today he was very uptight after work and quite negative, saying everything he does breaks etc. he had a bad run around tea time where a few things went wrong (dropped a sauce bottle, cat hurt his hand, stepped in food on floor) and it basically ended with him slamming something sharp into the counter top. I yelled at him to put it down, that it wasn't on etc and he has now basically retreated into himself and is lying in bed, either asleep or pretending to be asleep. Meanwhile I am trying to run a normal evening for the kids. <br>I really don't know what to do. His behaviour is crossing a line massively for me, and I'm really disappointed he let himself get to that point. Also makes me feel unsafe and unsure about leaving the kids with him. <br>I'm thinking perhaps its the time to insist he starts daily exercise, to bring the stress levels down. And perhaps his meds need a review. Far out. Any wise words for me???
