What made you decide to find love & start families?

I'm 24 & isn't into finding love or getting married because it all takes work (that I don't feel like doing) & I fear it'll NEVER work out. Nothing hardly works out for me or my family. Plus, I fear no one will love me or vice versa since I'm so withdrawn. But there's a tiny part of me that taunts me over the fear of being old & having no one (no husband, kids, or grandkids) around to love me. What should I do?
