Congrats Aleena! So glad you came to a decision. Best of luck to you, and know that there are plenty of people who have gone through/are going through the same situation.
I saw your previous post about lack of support, and if it makes you feel any better, my parents had to leave their native country to be in the US for my healthcare. They gave up their careers, their families, friends, social status, everything. My mom gave up her career as a nurse to stay home and care for me full-time and my dad's worked on his own to support us for 20 years now. We too had to get by without any support. My mom's family was in a different country and my dad's family in the states didn't care (they still don't) much for us because they view the illness as a burden and don't want to risk getting involved. It's been incredibly hard, but if my parents, with their broken English and one income, can do it, so can you!
Anything's possible, and a happy life for your child is definitely attainable too
