Trying and trying

After spending many hours and time on the first model with all the things i wanted to work and do, nothing was going along and the subdivision not showing up to make things smooth or over lapping 

Everything that I'm trying to do and fixing just goes worse each time. 

 it looks perfectly fine when making and having the sides and corners done and double line for the side so that the sides will be smooth to a minimum.

 

This is what happened that shocked me when i smoothed it, even trying to fix and change lines and it didn't work. Its taking me few days to get it right and move on to have a brake and than back to it incase i was spending to much time on it that i cannot think of anything. At the end, I have given up now. its just not working and made the decision that i would be better to start over again instead of wasting more time on it since i had made my working object as one whole mesh than separate. Lesson learnt to do things in parts would be better so it would be easy to be done again in mini parts than as a whole.
