YANBU to have feelings
but you need to stop wasting your life and make the most of it! (which is harder than usual in the middle of a pandemic I give you that...)
Kids change everything. Or they should. Kids become your priority. Yes of course you can still have a life, no one expect parents to become martyrs, but once you are a mother, your kids come first, and your life becomes a family life. As it should.
Make the most of being child-free for now! Regardless of what MN tends to think, kids don't stop being your kids once they reach 18, you still support them through their life, emotionally and financially as much as you can.
Be selfish for now. Do what you want, sleep when you want, travel where you want (well.. plan to at least....). Make the most of your youth now, so once you have them, you have achieved pretty much all you wanted and the rest is so much easier.
I have 4, and it's only financial that I haven't got more. I am still working, I am still achieving a lot, but it's not the same, and I wouldn't want it to be the same. I made the most of my youth and the most of my DH pre-kids, and I am so grateful I did. You can never go back to these child-free years, and they make years with your kids so much better.
33 IS really young. I wouldn't wish it on anyone to have kids much earlier than that.
