The first step is to understand your part about why the communication has stopped flowing freely between your family members.
Have you been hurtful or dismissive when speaking to them?
Are you open to their concerns no matter how "left field" they seem to you?
Communication stops because the two sides cannot see each other's viewpoint and it's important to start with understanding each other to be able to talk calmly and openly.
This may even involve putting your interests on the backburner for a while.
