home

When someone tell you " there is no place like home".. what does the word "home" means?

these are some of the meanings I found:
1. A place where one lives; a residence
2. The physical structure within which one lives, such as a house or apartment.
3. A dwelling place together with the family or social unit that occupies it; a household.
4a. An environment offering security and happiness.
4b. A valued place regarded as a refuge or place of origin.
and the list goes on...

Amongst the meaning given above, only no. 1 & 2 is probably the most accurate description of my home. Unforunately for me, I do not feel that I have a family that occupies it, it is NOT an environment that offers me security nor happiness or even a place that I take refuge in.

To me, "home" = prison.
