Married childless couples

Do you think married couples without kids can be happy and have a fulfilling life?

I am on the fence about having kids and I dunno if I want them. I love kids but unsure I want to make a lifetime commitment of someone really depending on me. I think it scares me because of the environment I grew up in and because of the mental illness that has ran in my family. I dunno and because of younger ppl than me that I see now days. I also struggle with depression on and off and although I am a high functioning adult with depression I wouldn’t want my kids to go through that I would be way to worried. 🤷🏻‍♀️
