Did I over react?

So I recently had a nervous breakdown from all this virus stress put on us financially along with other factors that emerged all at once including a coworker passing away from the virus. Regardless I was embarrassed. So I made fun of myself to make light of it. But then just a few moments ago, my wife chuckled and so I asked why and she told me our friend (mainly hers) was mad and talking shit about me behind my back. Now I love my wife and wouldn't give her up for anything. But I was actually hurt that she is just letting people insult me or make jokes about the. Now, I just caught her laughing whenever her friend bad mouthed me I was hurt because if nobody in the world had my back I expected my wife to have it. She claimed ty that she felt she could laugh it off as I had. Now she has a horrible past that made her have a few issues beyond her control. Many of those issues stem from exes that had beat her to the point she was hospitalized several times. We were told to file unemployment for the month of April. I know she is gentle and non confrontational and that her laughter is usually just her way of dealing with stress and usually has no control of it. Am I wrong for thinking my wife should have stood up to her friend for me despite her issues?
