wantobehealthy....I suspect that you have internalized the attitudes of the adults around you when you were growing up.....?
When I am writing professionally or speaking in public...I use my best language skills...
However when I am with my own peeps or writing on this forum I take any number of liberties with the informal language...Sometimes, I deliberately use certain forms for a specific "effect" in my expression.
I hope that I will be forgiven.....
