As a believer in Christ, I resort to the Bible for the toughest questions life throws at me. In chapter one of Luke’s gospel the story of two miraculous births are recorded. There are others in the Bible such as Sarah and Abraham. I can’t answer your questions about whether to have a child or go back to a higher dosage of Effexor but I do know God specializes in tough situations. I’m going through my own withdrawals from Venlafexine, having been on it for approximately 5yrs and weened myself from .75 to .375 in the past 6 weeks or so. It hasn’t been any fun but it’s a decision I’m sticking with although I still feel a bit dizzy at times and like you have the nausea but not so much the emotional problems albeit I’m still lethargic. I’ll be 69 in Dec and my wife says it’s also old age but I’m not swallowing that” pill.” Lol. I’ll leave you with one of my favorite Bible verses. Philippians 4:13. I can do all things through Christ who strengthens me and equally as powerful, first John chapter 5 verses 14 through 16. And we know that if we ask anything according to his will we know that he hears us and gives us the petitions we have required.
I’m hopeful this brief exhortation will help you through this tough time. Best Wishes
