Dear Peter,
How nice to hear from you again!I think it is natural for you not to get used to the life there.Here I have some suggestions for you.
First of all,you should respect the local customs there and try to involve yourself in the natives 'lives.(高分句型一)Just as the saying goes,"When in Rome,do as the Romans do."Besides,don't be afraid to communicate with French students and make friends with them.Friendship will bring you happiness.Finally,it is suggested that you participate in more activities,which may help you relax and have fun.(高分句型二)
I do hope my suggestions will help.May you adapt to your new life and enjoy your stay there.
Yours,
