I've been thinking a lot about this topic since I've seen it.
For starters, Ms. x0Kiss0fDeath (lol), no matter your reasons to have or not to have children are yours and whatever you decide is the right one for you. You don't need to justify your decision to anyone.
Regarding the subject of not having family support, I will tell you that I understand entirely where all of you are coming from. I moved 750 miles away from home to marry my boyfriend and start a new life in 1990. We were married for a year when he told me that he changed his mind on having a child with me. The next week, I found out I was pregnant. We ended up splitting up when our son was six-months-old and I was 22. I stayed in Houston with my son because I had a job and an apartment. I could only afford to see my Dad and sister and her family once a year so I had no choice but to be independent.
I met my Englishman in 1993 and moved to England in 1995. He's from the north but we lived in Reading so again, we were far away from any family. Interestingly, my husband told me that he was happy just being a stepfather and didn't want to have a child when we were so far from any kind of family support. I agreed with him. In 1997, I missed one day of a BC pill and in September, we welcomed a son. In 1998, he got a job in Europe traveling to various countries but was based in Germany. He moved away and I stayed in Wokingham by myself with the kids because my son was already in school. We saw each other 72 days a year for four years.
In 1999, my husband bought us a house near his parents in Bolton so I could have "support" while he was away. I thought it was the best solution and I envisioned my husband's family helping me since their son was in Europe and they lived four miles away. It turned out to be a HUGE disappointment. They visited us once a month, if I was lucky, for four hours.
One day, I discovered my MIL would take three buses to visit her daughter 10 miles away and she hardly saw us. That was the day I finally decided that I was independent enough to not need "family support". If I saw them for four hours, fine. If I didn't, that was fine too. I ended up having another child in 2001 and I was good on my own. In 2002, my husband lost his job and came home due to the telecoms crash. In 2004, after we exhausted our savings, we left the country and moved to the US to live with my Dad until we could get my husband a "Green Card". Guess who cried the hardest when we left? The in-laws.
Our family ended up moving to Chicago, Austin, Atlanta and back to Houston within four years. We have no family close by or very many friends. My father passed away in 2011. I don't pine for "family support" any more. I think we do pretty well. My children are grown now and my oldest is a father. I think that the best thing I can do for him is to give him the space to do things on his own. He'll have to, as my husband and I are moving to England in 2019.
So, in all that rambling, it's wonderful to have family around but at the end of it all, you'll have to do the hard stuff on your own. Plus, you live in a world of the internet and social media and your family is never too far away because of it.
Btw, my father was a Mexican citizen and his daughters were foreign-born in the USA. It wasn't so bad being showered with attention when we visited Mexico. Our cousins used to think we were very exotic and found it crazy that we spoke Spanish with an American accent and that our lives were so different. It was very nice indeed
