Your thinking is just fine. I am the same way, and I get accused of over sensitivity. It's the nature of depression though to take things more sensietively. Let me guess, you have been buned a lot before by a lot of different friends. Isolating yourself is a protection thing, that allows your brain to get past the hurt. Unfortunately, friends and family that don't know anything about mental ILLNESS judge people for doing what they need to do to stay out of that horrible pit of depression.
