This is an elementary age paperback I read in the 1970’s. It is about a girl who had friends in school but they turned against her. She had to find new friends, and she made many different kinds of friends, like adult friends, that she never before paid attention to until she had to make new ones.

Blubber by Judy Blume

Maybe one of the Taffy Sinclair books, by Betsy Haynes?
I wonder if it’s CLAUDIA by Barbara Brooks Wallace, 1969. it has been republished with a different cover, but this is the scholastic edition here: http://www.librarything.com/work/360965/book/113720084
My suggestions:
Best Friend, by Shirley Simon, 1964
Claudia, by Barbara Wallace, 1969
Ellen and the Gang, Frieda Friedman, 1963
Gertrude Kloppenberg (Private), 1970
The Janitor’s Girl, by Frieda Friedman, 1956
I would like to add The Popular Girls Club by Phyllis Krasilovsky to the list. My copy is not a paperback and the girl doesn’t make any adult friends that I recall, but her regular school friends desert her and she has to make new friends. Seems to be a common theme with these books in the 70s.
I believe it IS Best Friend by Shriley Simon. I am going to purchase it. Thanks for solving this mystery. I remember jenny, Dot, Edythe. Some things are a little different but I will post back if it is the one!
I was able to find a detailed review of the book Best Friend by SHirley Simon, and it is the book. Thank you so much. This mystery is solved.
