First: No one has more trouble than another because each person is their own and deal with their situations in their own individual manner. You're not a burden here and you sure as hell don't deserve to feel this way. There's nothing to feel guilty about.
Second: Everyone relapses back into their depression; it's so easy to do. I've slipped back into mine plenty. The only difference is the amount of experience I have in knowing how to manage it to get through another bout. It's the same with anxiety. Don't stress yourself too much about the future that could probably happen. Focus on now. You normally do good at work and you didn't do so great today, everyone has those days. Just take it day by day. Learn from those mistakes and keep going. If the conversation made you upset, talk about it with someone you trust and feel safe with. Talk to your husband about how the news being on all of the time isn't helping your situation.
Third: Breathe. You got this and you're going to get through all of this craziness. Something my grandma always told me, "Everything works itself out in the end." Nothing can ever stay all good or all bad, it always falls back to the middle. Same thing for this situation.
I have faith in you.
