Hello Michelle,
I understand your upsetment about what is going on.
As Robin said, each person diagnosed with schizophrenia responds differently to the medication, as well as being an individual in their response to what happened to him or her. Your father may feel that it will be too stressful for him, or that, perhaps, others will pcik up on the fact that he has a mental illness, when they meet him.
Offer to go with your father to these events, and let him know that if it gets too much, you will respect his right to leave early. As hard as it is, sometimes people diagnosed with schizophrenia have to take moderate risks. Only by taking one or two chances will your father know his limits. He can always opt to bow out of stressful situations after he has attempted to be a part of them. If the stress gets too much, please remember all the good things about your father (that he loves you, for one) and that he probably would rather it be different.
Find things to do together as a family that he can take a part in.
I hope this helps. I believe you've written to the Connection before. I want you to know that you are not alone. I wish you to have a good night and do write back if you feel the need.
Regards,
Chri
