i could be a smart a** and say, "if you have to ask, you don't want one." but that's a facile answer to a complex question. there are a lot of variables. let me give you a bit of my personal history as an example.
i grew up in a dysfunctional, abusive family. i was what some psychologists call the "sacraficial lamb." whatever went wrong in the family was my fault. as a teen (back in the early 60s) my motheer took me to a psychiatrist and essentially said, "fix him. there's nothing wrong with anyone but him."
like you, i have been clinically depressed for almost my entire life. about 5 yrs ago i was diagnosed as bi-polar. this dx was seconded by a second, independent, psychiatrist.
my wife and i have travelled all over the usa and eruope. we have been places and done things that most americans don't even know exist. but we have done it at the expence of not having children of our owm. i will be d*mned in h*ll before i would put another sentient being through the h*lls that i experienced growing up. child abuse isn't in the dna, but it is passed on in families from generation to generation. depression is now considered a genetic disease. why would i curse my child with abuse and mental illness? not me. no. not in this life time.
this is my decision and my wife's. when we first got together over 30 yrs ago, we talked about it and we have lived the lives we decided upon.
this is a personal decision. i can't make it for you and your priest, rabbi, or minister can't make it for you. we can point problems and benefits. one thing i can say from personal experience, don't have a child thinking that it will "save" or "improve" your relationship. Babies take over your life and magnify existing relational problems.
hope this helps.
That light at the end of he tunnel? It's an on-coming train.
