Being blocked never feels great, but there are two things to consider. Part of the spiritual path is to stop obsessing over ourselves and to consider others. We feel uncomfortable about being blocked - something which is not in our control and MAY not have anything to do with us - but the person who has blocked us will also be uncomfortable. Their discomfort may not have anything to do with us, but we should consider it.

I block to protect myself - from drama, unpleasantness, or even a drain on my time and mental energy. It could be anything.
