Why do i "fear" nostalgic,old,familiar things?

Many of us fear feeling too deeply. I'd guess that is why so many of us escape into things that take us away from reality: soap operas/entertainment TV; drugs, alcohol, other addictions such as promiscuous sex that could hurt us, gambling, compulsive shopping that ruins our finances, etc. An online friend introduced me to vippassanna and sent me a wonderful poetic one-page article about it (lost it) and that helped a lot. Taoism and stoicism has similar teachings or thinking. It helps.
