I would point our two facts:

#1) No expectant mother is guaranteed a healthy baby. Things that can go wrong - right up to the day of childbirth - can result in a baby born with serious "challenges." You really don't know what the baby will be like, until after it arrives. What does arrive may seriously disappoint your hopes and expectations. I believe everyone needs a contingency plan for that. (How supportive would grandparents be of a "special needs" child?)

#2) There is no psychotropic medication on the market that does not pose a possible threat to the normal development of the unborn child. (Still, there are mothers who have had healthy babies after taking meds.) How much risk is "acceptable?"

These are hard, cold realities.

If you have been getting meds for 9 years prescribed by doctors who strongly believe in the "chemical imbalance" theory (and most doctors seem to), then you may have come to believe that you would be worse off without meds. That may not be true. Doing the math leads me to the conclusion that you started meds at age 13. By now, you are conditioned to believe that you must be on medication. Maybe it is helping. Who knows? Have you ever been off meds long enough to really know how you feel drug-free. Doctors tend to be biased in favor of meds. And, yes, I will say it is a bias. Prescribing meds is what doctors do. That's all they really do. They diagnose diseases and they prescribe medical treatments. That's what having MD after the name means. They don't have any special wisdom about life that the rest of the population lacks. Going to medical school doesn't give you that.

Anyone who is having a lot of difficulty with life probably does get depressed and probably does qualify for that diagnosis. I'm never convinced that the fundamental cause is mainly some disease of the brain. I guess that's my bias.

Having children is one of the responsibilities that helps a person mature. I think that having a child could help a person "outgrow" depression. To be honest, though, I would hesitate to bet a lot of money on it. Exceptional people do overcome all kinds of things. I guess the ultimate question is whether you have what it takes to be exceptional.
