Hey Blanca, glad you found somewhere. Are you teaching in Paris?
Paris is very famous for exactly this thing. You may find in smaller towns, especially in the extreme north and south of France that they are more friendly, more tolerant and more open minded. That said, if not for sarging, try and talk to EVERYONE there in Paris. You'll learn a bit of vocab every time (and how the verbs are conjugated). If you make a point of going to the same bars and cafes (breakfast is very much a cafe thing in France, as in Italy), the barman will surely recognise you eventualy and also will identify you as someone who lives in Paris, not a tourist (who he'll never see again). He will therefore be obligated to show a little kindness in order to keep your business. You'll also have some social proof with that, especially if he were to address you by your first name.
Breaking into a new community is not easy, especially in a more insular culture. That said, picking up (not Fclosing) is probably easier as they have a more apporachavble attitude in continental Europe. You're also not French and speak French, which is a massive DHV.
Give it time, you'll be loving it before long. Don't feel bad if it takes a while to build a circle of friends also
