Child visitation in texas, what do you think I should do?

OKAY THE FATHER OF MY 3 YEAR OLD SON DOESNT EXERCISE HIS VISITATION ALOT AND HE SAID THAT HE IS GOING TO PICK OUR SON UP ON JULY 1ST FOR HIS 30 DAY VACATION PERIOD WHICH HE HAS NEVER HAD THE CHILD LONGER THAN 2 OR 3 DAYS AND I AM ALLOWED TO HAVE THE CHILD ON ONE WEEKEND I CHOOSE IN JULY HE SAYS HE IS GOING TO REFUSE TO LET ME SEE HIM AND HE IS GOING TO REFUSE TO LET ME TALK TO MY SON ON THE PHONE AND HE SUFFERS FROM MENTAL STUFF LIKE BIPOLAR AND ANGER ISSUES AND SIEZURES AND I AM AFRAID TO LET MY SON GO WITH HIM BECAUSE OF HIS MENTAL STATE AND AT THE SAME TIME I AM AFRAID TO GO TO JAIL FOR NOT GIVING THE CHILD TO THE OTHER PARENT. WHAT DO YOU THINK I SHOULD DO? AND DO YOU THINK THE JUDGE WILL PUT ME IN JAIL FOR TRYING TO PROTECT MY SON. AND WHEN THE FATHER IS ON HIS MEDS HE IS IN THE RIGHT FRAME OF MIND AND ACTS RIGHT. BUT LATELY HE HAS NOT BEEN ACTING HIS SELF AND I THINK ITS IN THE BEST INTEREST TO NOT LET THE CHILD GO BUT AT THE SAME TIME I DONT WANT TO GO TO JAIL. DO YOU THINK A JUDGE WOULD PUT ME IN JAIL AND THE THINGS GOING FOR ME IS HE HAS A MENTAL HISTORY THERE IS MEDICAL RECORDS ON THAT AND I HAVE NEVER BEEN IN TROUBLE WITH THE LAW. AND PLEASE I HAVE ALREADY TALKED TO A LAWYER SO PLEASE DONT TELL ME TO GO TALK TO ANOTHER ONE. THE CHARGE IS INTERFERENCE WITH CHILD CUSTODY AND ITS A FELONY 6 MONTHS TO 2 YEARS IN PRISON.
