I understand the meaning behind your response in this situation. You reacted to the insults, or rather the source of what made you feel offended, by using the brain's habbit of adapting to one's circumstances and surroundings. Since we know that those who get uncomfortable consistently are likely to get dragged down by what forces them out of their comfort zone, and the heat of the moment may escalate and worsen the situation itself. The consequences snowball. That's why you lowered your sensitivity and felt more strengthened. Since by distancing yourself from the problem you get the idea that you are less invested into it, and that suppresses emotions and anxiety.

Moving on can be advantageous if done by thoroughly analyzing the problem and searching their causes, digging down to find the roots behind someone's behavior and then judging them impartially on what you know. You get a better grasp on why the situation played out the way it did and you have a larger variety of solutions on your hand because of that, you can get connected to the other person. But that's why the difference between carefully crafting an answer and simply distancing yourself from the issue is insurmountable. Most of the times, not bothering to give a situation enough care leads into senselessly escalating the issue, because the barrier between not investing yourself into something and blankly not putting enough thought into it is so thin. It's extremely hard to handle a situation you are not feeling comfortable about, and lots of people I know can relate to that.

But not exiting the comfort zone, especially regarding situations you find yourself frequently in, is counterproductive. Because untouched stressful situation in which you found yourself in before always add up with the time. And the same experience which gave you the impression of strengthening and possibly improvement, earlier in the day, will only provoke more stress when you find yourself in a similar context, at which point you are rewarded with frustration more than anything. This is caused by a simple fact. When you are aware of the reasons behind your actions and confidence you are also feeling more justified in how you react. Therefore any consequence to come will not hit hard, because at that point, you already know how to explain impulsive reactions. And as I said before, it really helps in grasping the situation better and finding out solutions. Which is more optimal than stopping to care altogether, it's more upholding. More constructive.

Therefore we can talk about anything you want; I can tag along. But be as honest to yourself as you can.
