Am i a mental case because of this?

I do not think this is all that unusual. It seemjs to me that you are unwilling to let go of these good times and the innocence of childhood memories. Many people feel this way about their roots. The main problem to me seems like you are in the here andnow and focussing on the past. to me this means something about now must be unhappy. You should be making new,happy memories now to look back on in the next decade. It seems you mis the support of the family when you where a child,look back to see why.
