Does anyone here have only child feel happy?

I feel like crying I had a horrible csection had organ failure infection was hospitalized it was painful

My child is so happy so social and I feel guilty I want to have another baby it took me one year to fully recover but I'm scared I haven't talked to a mom whose had children after a csection but I've seen some post on here that it could be dangerous. I've thought about adoption but have no idea how to do it it would be a blessing for my family.

I remember growing up with my sibling playing together we were best friends and I don't want a only child to be lonely.

The cousins live out of state I'm not sure what to do.
