That sounds so frightening and worrying, synonymous, pleased your husband is on the mend but the time shortly after discharge can be a worrying and exhausting one, it perhaps doesn't feel totally safe. It isn't unusual to react when things are getting better. You are allowed to howl, the fear has to come out somehow, I hope you both have some help, if your husband has been your carer do you need some professional help in the short term? Otherwise take up any offer of practical help from family, friends or neighbours whether to pick up a newspaper, cut the grass or put the rubbish out. Being at home with you will help him hugely but if you can encourage your husband to be honest about how he is feeling you will worry less, Should either of you be worried then do seek medical help. No one will mind. It's been a horrid time, be kind to yourself now, hoping he is so much better very soon.
