why do I feel so sad after arguing with people?

I originally posted this comment on Reddit, but I got no answer from anyone, and my feelings about this have not changed, as a matter of fact the same kind of issues with work colleagues keep repeating themselves:
Even when I Know I am right, even when physical irrefutable evidences prove that I am right and the other person that I had a discussion/argument with was wrong, I still feel like crap afterwords. Sometimes is easier if I am the one who is wrong, because I could simply admit that I was wrong and move on. But that becomes impossible in some situations where not calling out a colleague who was wrong will either cause problems to others or cause me problems. And I am not talking about physical violence, not even screaming matches. Just disagreeing with someone over something or some situation that opposes me to them, that is enough to trigger this feeling of stress, hollowness inside, wanting to quit everything and just run to a deserted place where I would not have to see or talk to anybody. After the discussions my head starts to spin at 100%, thinking and reenacting the scene in my head, analyzing every word I said, every gesture... it is torture, and I can't stop. This has been happening a lot at work, to the point where I wonder if I should just quit (I know this is not the solution, all other jobs will be the same).

Hello PtrLopes: I see this is your first post here on PC. So... welcome to Psych Central.

As you are perhaps already aware, we here on PC cannot offer mental health diagnoses. Plus I'm not a mental health professional. So I can't really suggest much with regard to the experiences you're having although I would have to say they are familiar to me. My inclination would be to suggest your reaction to arguing with people may have to do with low self-esteem. But that's just a guess. A couple of things you might take a look at are the concepts of childhood emotional neglect (CEN) as well as the highly sensitive person. Here's a link to the CEN forum, here on PC, along with a link to the Coping with Emotions forum which is another one that might be of interest:

And then here are links to 3 articles, from Psych Central's archives, 1 on CEN, 1 on the highly sensitive person, & 1 on self-esteem :

One thing you might do, here on PC, would be to take some of the quizzes & tests that are on offer. There's a link to them in the banner at the top of the page. However here's another link as well:

I hope you find PC to be of benefit.
