Here's some advice I have. Know that depression and anxeity are more from one's experiances than through their birth, if that is all you suffer from on a phsycological level, it cannot be inherited. You being a virgin is certainly a blessing, because you can clearly think about if and how you want to have kids, you'll probably be more responsible with your sexuality as well. Also, childeren are blessing and think about the cost will just force you to be disuaded from having kids, most parent I know didnt plan their finaces just to have kids. Settling down is the most important. The way I see is that you seem very aware and vigilant against contuing generational ills to the young, I would take that as a sign that you would be eager to cure those ills and try to do better. I have alcoholics in my family, plenty of abuse, but I should expect that someone aware like yourself would avoid such vices. Usually eager young men clean their acts for their families if have a loving heart. I'd like to say that you would make a great father. Don't sterilize your self, that'll just make more stagnation and death in your. Having kids would bring growth and life.
