Personally I don't think you understand my position very well, or perhaps you understand it the reasoning intellectually but don't realise just how much of an realistic effect it can have on someone (In the same manner you react negatively to someone who would self-harm.) I think the easiest way to clear up this issue is by getting someone (Preferably an INFJ) who has undergone a constant period of numbness, or endured depression otherwise it's all speculation of what it feels like.
In the same manner I can't conclude that I fully understand depression because I have never been in that state before. However I have experienced long term numbness and it's something that I'm extremely concerned about for a long period of time. Forgive me, but it really doesn't sound like you have experienced anything to that effect although I could be entirely wrong. You could clear that issue up for me.
One thing I'll agree with is that your emotions are yours, and there isn't any right or wrong emotion. But if you are going to attack me for not coping well, I sure as hope you understand my position first and the position of others, and that everybody is along the same line of thought. It's not good you thinking that these people are talking about stress, when in fact they are experiencing burnt out for example.
PS. Because I'm in a Ti war mode. Your experience of maintaining friendship doesn't sound that unusual from an introverted perspective. But I suppose you were just raising the point that we are in an arguing mode, and that I was definitely on different wave lenghts.
