I don't want to tell you what to do, in your situation in Cuba.
I really know how terrible is, I live it myself long time ago.

The only advice, (based on my own experience lived in such situation) I could give is this:

• refuse to comply - here is a video explaining how others did it long time ago. Nothing can be imposed if people refuse to comply.
• stand your ground, no matter what. I know this is really hard to achieve, especially when you have kids, family, but there's no other way against totalitarianism, you have nothing else to lose.
• mass disobedience. It must be in mass, otherwise very few things you can achieve, maybe only some at personal level, but when is about for more important things, it must be at mass level.

Of course all these must be decided by yourself and people around you and decide when is the right moment. Only you can know when is that moment.
