I know I'm not sz so ignore if you please. DH and I come from a long line of MI. We knew this. We decided as long as we are pro-active with his health he'd be "fine". We did pass MI to him. However he is generally more happy and healthier than we where as kids. For us our MH team is very important in helping us raise a happy healthy child. If all I manage to do is screw him up differently and show him that there are resources to help that's good enough. I don't expect a dr. or lawyer but I encourage anything he wants to do that still fall under the heading Happy & Healthy. If he chooses not to have children I'm fine with that.

Another option is adoption it's harder with MI but with letters from your MH team you can. best of luck.
