Modern society is one that tends to be antisocial in that it enables people to feed social needs through TV. Movies and soapies and news shows have many aspects of normal social interactions without the physical or emotional risks of two way social intercourse.
Interactive media such as email, blogs, and video conferencing such as cyber sex; is also safer than traditional interactions.
In a work situation we have a script to work from and while we are in business mode genuine more in-depth social intercourse can be avoided or may even be taboo.
More people today are short sighted because they have less opportunities or motivations to go outside and look at the horizon. If we spend most of our time reading books or inside small rooms or watching TV up close, during the formative age for eye development our eyes focus on things close to us making us short sighted.
Similarly if we are in constrained social environments when we develop our social makeup we will become more or less inward or outward looking in a social sense.
According to Maslov's Needs Hierarchy higher needs will not concern us while our baser needs are not seen to be met. A person who is focused on surviving from day to day or building a career will often put on hold less pressing needs for social interactions or self actualization or discovering the meaning of life.
In our society your situation is sadly very normal.
