It is for sure that there is some incident happen in between these 7 months.U try to talk to ur sister ,it is the only way to treat her.
If she doesnot talk to u then u should take her to psychologist for better Counselling sessions.
U must not scold her,or u should watch that ur parents also should not scold her.
Do not let her alone,she may take wrong decision.
