Sorry to hear you’re in such distress! The lockdown is putting extra pressure on everyone. I would say to get in touch with a crisis hotline and talk to them as they will have qualified, caring people who can help connect you to resources.
Stay strong and maybe give your husband space. Hopefully he will come back around to talking. I know how difficult it can be to keep up hope, but it’s important. Your plan to see a doctor is a good one.
Stay strong and stay well!
