You poor thing.
Glad you are feeling a bit comforted now.
For today, I would just concentrate on getting yourself "up" a bit. You've already started by making this thread and receiving encouraging replies.
Later today/tomorrow, maybe (with our help, if you like) you could start making a game-plan to take control of this.
Anxiety feeds on itself and it's hard to break the cycle, but there is a lot of help out there.
Make a comforting drink, keep posting here and put on some music or calming hypnosis playing in the background. Stay away from 24-hour news on TV or anything that stirs up emotion/anxiety for you.
Make an appointment with your GP for medication or talk therapy/counselling - whatever you decide between you that would be best for you.
Try this guided meditation. It's lovely:
If you type "anxiety relief" in youTube, it will come up with hundreds of videos offering calming music and guided meditations - all for free.
When you are feeling stronger and when you and your DH have time to talk, see if there is anything you two can work out to make your lives run smoother. For instance, does DH often run late for work? Why? What could he do to change that? I think your morning starting off right would help set the tone for the day.
As for the rude person you spoke to, there's not much to be done about other people's rudeness, I'm afraid. If they are always rude, but part of your life, try and minimise the time you have to spend with them or start a thread about this person so we can help.
Good luck.
