Hey, French speakers, help me write the sequel?

Do you speak French?

The sequel to Lesbian Crushes and Bulimia (1989-1990) will be Lesbian Crushes in France (1990-1991). More dysfunctional behaviour, different country.

Could you give me ANY amount of help correcting the phrases below? They are numbered for easy reference. When one is resolved, I shall remove it. So I still need help with any that you see here.

Thank you so much,
