Hi MM, I am sorry you are having a very challenging time.
Very good suggestions were made in posts above.
I do understand that you report becoming too confused to think about which strategy to employ.
Are you able to check-in with your husband and/or your son in order to help you re-orient yourself as you become more grounded in reality?
I am hoping they can be Present enough to assist you in also becoming Present in the Present Moment.

I hope you can pursue this without delay.
Please do keep reaching out here.
