I need to hear successful story on adoption

I'm in my 32s with my first pregnancy and considering adoption. Here is my situation, I came from a very conservative middle class social background. My parents are divorced, my father was remarried recently, my mother was a single mom of four children and she also not looking forward in raising any more child and still couldn't take the disappointment of my unwed pregnancy well. ( She is a very high expectation and conservative kind of mother ) I m working in health care industry and used to be more financially stable 2 years ago when I was working full time. But I'm now doing full time post-grad study in this very competitive field ( got paid from study but very little comparing to time consumed and all the night shifts and calls ) and also paying for my home loan with my family support . So I'm actually depending on my family financially. Now I'm taking a year off from my study b/c so much stress I afraid that would ruined my career . I really freaked out when found out I was pregnant cuz I never that motherly type and not ready to be one. Due to my family background I strongly against single parenting for a child, unlike some single friends my age who desperately want to have children so much before theirs biological clock ran off. I know that in a few years I will be more financial stable but still not that great and not up to the standard I expect myself to provide for my daughter, like private school, extra curriculum study and most important quality time with her, etc. Although I felt so miserable through out the pregnancy especially now at 8 th months and never excited to be mother, I know I love my child and wanted all the best for her. I have been reading those post for a while and find many birth moms morning in agony but also find a lot of miserable single moms while google along ( some even resent their child ) Please all birth mother, please tell me if you felt you have make the right decision? And if you were able to achieve your career path and fulfilled life not just surviving it and still copping with the feeling of losing your child? I do realize grief and sorrow are part of relinquishment from your child but do you feel you are making right decision anyway? Or regret it? Please tell me if you finally healed emotionally and how did you manage to overcome the sorrow. How long after adoption ? I know these question may sound too hash but I really need to find out before making final decision. I really can't discuss this issue with anyone around me. No one I know was ever in this unwed and unplanned pregnancy situation. My mother keep screaming and upsetting herself every time I bring up this subject. I only have my therapist to talk to without any prejudgement comment but he also admitted that he is not very familia with adoption cases. P.S. I live in the country where adoption is not well spread and not well organized. If you want your child to be adopt you usually need to put them in orphanage home first and someone will pick up your child or just live there until the child grow up and be labeled as poor opportunity child. You will never be able to know who adopt your child. But in my case I do private adoption and select this couple myself. In my country women with unwanted pregnancy usually have only 2 choices, illegal abortion ( yes, I said illegal abortion because it still is but thanks to many organizations trying to make it legal now so women have more choices ) or single parenting but also poor law enforcement
